Low Voltage Relays Explained: Types, Functions, and Applications

In the complex world of electrical systems, relays play a crucial role in ensuring safety, efficiency, and automation. Among these, low voltage relays stand out as versatile components that manage and protect circuits operating below 1000 volts. Whether in industrial automation, residential power distribution, or commercial infrastructure, these devices act as the nerve center of electrical control and protection.

In this comprehensive guide, we will break down what low voltage relays are, explore their types, explain their functions, and highlight their diverse applications across industries.

What Are Low Voltage Relays?

A low voltage relay is an electrically operated switch that uses a small control voltage (typically below 1000V AC or DC) to switch larger electrical loads on and off. These relays act as intermediaries between control circuits and power circuits, providing isolation, control, and protection.

Unlike manual switches, relays automate the process of circuit management, responding to electrical signals, fault conditions, or system commands without human intervention.

Types of Low Voltage Relays

Low voltage relays come in several forms, each tailored to specific tasks within an electrical system. Here are the main types:

1. Electromechanical Relays (EMRs)

· Use a coil and a movable armature to open or close contacts.

· Provide physical isolation between input and output.

· Common in traditional control panels and basic automation.

2. Solid-State Relays (SSRs)

· Use semiconductors (like thyristors or triacs) instead of mechanical contacts.

· Offer silent operation, faster switching, and longer lifespan.

· Ideal for high-speed applications and environments requiring low maintenance.

3. Overload Relays

· Specifically designed to protect motors and equipment from sustained overcurrent.

· Available as thermal overload relays (using bimetallic strips) or electronic overload relays (using sensors and processors).

4. Time Delay Relays

Provide a deliberate time lag between the relay receiving a signal and switching.

Used in motor control circuits, lighting systems, and sequential operations.

5. Overcurrent and Short-Circuit Relays

· Detect and react to current exceeding preset thresholds.

· Essential for system protection against faults and overloads.

6. Voltage Monitoring Relays

· Monitor voltage levels and trip when voltages fall below or rise above safe limits.

· Protect sensitive devices from under voltage and overvoltage conditions.

Functions of Low Voltage Relays

Low voltage relays serve multiple vital functions in electrical systems:

1. Switching and Control

Relays control the opening and closing of power circuits in response to low voltage signals from controllers, timers, or sensors. This enables remote and automated control of large electrical loads.

2. Protection

Relays detect abnormal conditions like overloads, overcurrent, under voltage, and phase failures. When such conditions arise, they disconnect the affected circuit to prevent equipment damage or fire hazards.

3. Isolation

They electrically isolate control circuits (usually low voltage, low current) from power circuits (high voltage, high current), ensuring safety and reducing interference.

4. Signal Amplification

A small control signal (from a PLC, sensor, or microcontroller) can trigger a relay to switch much larger loads, effectively amplifying the control power.

5. Automation and Sequencing

In complex systems, relays help sequence operations by ensuring that processes occur in the correct order and at the right time intervals.

Applications of Low Voltage Relays

Low voltage relays are the backbone of automation and protection in various industries. Here are some key application areas:

Industrial Automation

· Control of motors, pumps, conveyor belts, and production lines.

· Use in programmable logic controllers (PLCs) and distributed control systems (DCS).

Power Distribution Systems

· Protect electrical panels from overload and short circuits.

· Monitor voltage and current levels in distribution boards.

Building Automation

· Lighting control systems.

· HVAC (heating, ventilation, and air conditioning) systems.

· Elevator and escalator controls.

Renewable Energy Systems

· Manage and protect solar inverters, battery banks, and wind turbines.

· Automatically disconnect faulty sections to prevent system-wide failures.

Data Centers and IT Infrastructure

· Ensure stable power supply to servers and networking equipment.

· Protect sensitive electronics from voltage fluctuations.

Transportation

· Railways, metros, and automotive applications for control and safety circuits.

Home Appliances

· Found in washing machines, microwave ovens, and HVAC units to automate functions and provide protection.

Advantages of Using Low Voltage Relays

· Enhanced Safety: Isolate control and power circuits, reducing electrical shock risks.

· Automation Ready: Easily integrated into automated systems for smarter operation.

· Cost-Effective Protection: Safeguard expensive equipment from damage due to electrical faults.

· Versatile: Available in many forms to suit different voltage levels, currents, and response times.

· Reduced Maintenance: Especially with solid-state relays, which have no moving parts.

Future Trends: Smart Relays and IoT Integration

As industries move toward smart grids and Industry 4.0, low voltage relays are also evolving:

· Digital relays offer programmable settings, self-testing, and event recording.

· IoT-enabled relays can send status updates and alerts to centralized monitoring systems.

· Energy-efficient designs reduce power consumption while providing reliable protection.

Conclusion

Low voltage relays are indispensable in modern electrical engineering, seamlessly combining protection, control, and automation. From safeguarding your home appliances to managing the power in a sprawling industrial plant, these devices ensure that electrical systems run smoothly and safely.

Understanding the different types, functions, and applications of low voltage relays empowers system designers, engineers, and even DIY enthusiasts to build safer and more efficient electrical setups.

As technology advances, the role of these small but mighty devices will only grow, driving the future of safe, smart, and automated power systems.

I was referencing the things put forth by OP, in order:

Huge wiring harnesses simplified: Cybertruck Guy and Radmad are both wrong, for different reasons.

Current industry standards don't have separate wires for each individual switch or control, either. They group several switches, lights, etc. that are nearby together, run them into a microcontroller, and put that controller on a vehicle bus. Currently that's usually a CAN (redundant, fault-tolerant) or LIN (neither, but much simpler) bus. This drastically simplifies wiring harnesses.

The main thing Tesla has done is change the DC voltage for that bus from 12 V to 48 V nominal. Since power is voltage times current, and wire thickness is dependent on current, this cuts about half the copper mass out of the power lines in the harness. The other (data) lines were already using smaller wires. The industry has been flirting with a 48V bus for around two decades by now; Tesla just went and did it and dealt with the engineering problems when they popped up. And this is a rare case where "they're a bunch of Silicon Valley nerds" may have helped: datacenters have been using 48V DC for in-rack power delivery for decades, so they had more familiarity with it than Detroit.

They've also adopted single-pair Ethernet (1000base-T1) for the high-speed entertainment data links. This technology has been in the industry since late 2016. It's usually integrated directly onto the custom ICs in ECUs. I remember another thread like this with a tweet where someone was complaining about the fragility of RJ-45 plugs and how that's disqualifying for a vehicle, and he's right, but single-pair Ethernet does not use those jacks; it's integrated into wiring harnesses with everything else.

Astronauts laded on the moon with altitude markers hand etched on the window: That was a backup system dramatized by the Apollo 13 movie. They had an inertial navigation system, like aircraft do, as their primary navigation.

Oh, and it's attitude, not altitude. Very different concepts that folks should not mix up.

Can't get a rocket off the pad without blowing up: Neither could NASA their first few years. Meanwhile SpaceX had 98 successful orbital flights last year, and they can reuse their boosters (the record is 18 times). But that's way off topic.

Tesla Model Y broke: It's not news when non-Teslas lose power steering, apparently. And I've had cars that took many more than three appointments to fix. We can throw around anecdata all day.

Series wiring like Christmas lights: Come on, you've got no basis for that.

It's like the Titan sub: Sigh. Really?

Okay, now to the RDN link:

the vehicle’s angular design and stainless steel body could pose danger to other road users

Absolutely true. Also true of almost every luxury pickup truck on the market. One example:

I'm all for figuring out some kind of regulatory regime to rein this in. Or maybe a modification of liability rules and increased insurance coverage minimums.

“The big problem there is if they really make the skin of the vehicle very stiff by using thick stainless steel, then when people hit their heads on it, it’s going to cause more damage to them,”

True, but it's not that thick or stiff; the speaker was speculating. Other have pointed out that "we shot it with a Tommy gun" is a lousy test because the bullets are rather low velocity. If you watch the side impact crash test, you can see the side panels visibly flexing.

And right after that, an IIHS rep said, “IIHS hasn’t evaluated the Cybertruck. The discussions we’ve seen so far appear to be based on speculation. I would add that our experience with Tesla is that they aim for the highest safety ratings in IIHS tests. We have no reason to expect anything different with the Cybertruck.”

The biggest problem with Teslas, from insurance companies' perspectives, has been that airbag-deployed collisions tend to result in totaling the vehicle more often than in other cars. Occupant safety, on the other hand, seems to be better than average. We've seen people walk away from their Model 3s after they got T-boned by speeding pickups (60-ish MPH in a 30 zone). We know this from accident reconstruction and camera data.

There's a linked video in the article comparing the Tesla Cybertruck collision to a Dodge Ram 1500. There are several others like it on YouTube (I saw one that had six trucks in it, all synced up). They all have the same flaw: they're comparing different crash types. The Cybertruck is doing a full frontal crash, where you drive the vehicle into a solid, immovable wall, while the others are moderate overlap crashes, where the hood goes over the obstacle and only the left 1/3 of the vehicle is obstructed, so the engine can deflect to the sides instead of going into the firewall and then the passenger compartment. The Cybertruck, of course, does not have a large engine in that space; it's mostly cargo storage. And we can clearly see it crumpling and the front wheel moving outward instead of back into the passenger compartment, like practically all cars do now.

(Some folks like to point out how the rear wheel breaks away, too: this is expected because it's a steering wheel, since the Cybertruck has four-wheel steering, and uses the same suspension technology as the front, instead of connecting the rear wheels more directly to the rear axle like most vehicles. Not completely directly, though, like the Chevy Corvair's swing axles. In any case, kinetic energy breaking the rear wheels off like that is energy that isn't compromising the cabin.)

The article addresses the "lack" of crumple zones:

Samer Hamdar, a George Washington University auto safety professor, told Reuters that while a lack of crumple zones concerned him, there could be other factors that accounted for it. “There might be a possibility of shock-absorbent mechanism that will limit the fact that you have a limited crumple zone,” Hamdar said.

I'm not going to speculate about crumple zones beyond the above ("the cargo area collapses, taking some energy with it; we have to see if that's enough to call a crumple zone, but it's not nothing") until someone tears one down and documents it. But crumple zones aren't the only means of keeping kinetic energy out of the passengers.

The rest of the article goes back to concerns about pedestrian safety, which seem to be the main substantive concern, and is noted at the end of this video:

And again, pedestrian safety is an industry-wide problem. We need another Ralph Nader, but demonizing Tesla alone (god it's so easy, Elon is such an asshole) only gives cover to the rest of the industry. And none of the tweets in OP's post spoke of this.

Top 3 Tips to Balance Performance & Power Consumption in Embedded Application Development

In embedded systems development, achieving the right balance between performance and power efficiency is an ongoing challenge—especially when working with microcontrollers (MCUs) and low-resource hardware. The right software design decisions can dramatically extend battery life without compromising responsiveness or reliability.

Here are three actionable strategies every embedded engineer should consider to get the best of both worlds.

1. Build Smarter Software with Efficient Code

The foundation of energy-efficient embedded development begins with how your software is structured and optimized.

Here’s what helps:

Choose better algorithms: Replacing inefficient logic (like O(n²)) with more optimized versions (O(n log n)) reduces CPU cycles and energy use.

Go event-driven, not polling: Event-based logic allows your system to enter sleep modes rather than constantly checking for changes.

Cut down on memory operations: Repetitive dynamic memory allocation increases power draw. Keep it lean and predictable.

Use hardware accelerators: Leverage MCU features like DSPs or crypto engines to offload work and reduce CPU load.

Pro Tip: Use compiler flags like -Os for size and power optimization. Tools like EnergyTrace or ARM's Power Debugger can help you find energy-heavy hotspots in your code.

2. Leverage OS and Middleware Power-Saving Features

Your choice of OS and middleware isn’t just a performance decision—it’s an energy one too.

Here’s how to optimize it:

Pick a power-aware RTOS: Systems like Zephyr and FreeRTOS come with built-in low-power features.

Use MCU low-power modes: Utilize deep sleep, stop, or standby modes to lower consumption during idle times.

Optimize peripheral management: Disable or scale down unused modules like timers, ADCs, or communication interfaces.

Reduce wake-up frequency: Combine tasks and delay non-critical activities to avoid excessive interruptions.

Scale clock speeds dynamically: Lowering clock rates during low workload periods helps reduce energy consumption.

Pro Tip: Use vendor-specific tools like the ST Power Calculator or Nordic’s Power Profiler to fine-tune system settings based on actual workloads.

3. Profile, Analyze, and Keep Optimizing

Even perfectly written code can consume more power than expected without proper testing and profiling.

Here’s your checklist:

Continuously monitor energy usage: Real-time power monitoring highlights inefficiencies across code paths.

Test in real-world conditions: Optimize based on typical usage patterns, not just lab simulations or edge cases.

Refine iteratively: Small updates—like fine-tuning interrupts or reducing wake-ups—can lead to major gains.

Slow down (intelligently): Your application doesn’t need to run at max speed—just fast enough. Slower = more efficient, when done wisely.

Pro Tip: Use simulation tools like Renesas e² Studio Power Profiler to preview energy impacts of code changes before testing on physical hardware.

Final Thoughts

In embedded development, managing the trade-off between performance and energy consumption is critical. But with the right software architecture, OS features, and continuous optimization, it's absolutely achievable.

By making informed engineering decisions, you can build high-performance, power-efficient embedded applications that last longer, run cooler, and deliver better user experiences.

220 Ohm Resistor: Applications, Characteristics & Design Tips

In the world of electronics, resistors are among the most fundamental and widely used components. Among them, the 220 Ohm resistor holds a special place due to its versatility and ideal resistance value for many common applications. Whether you're just getting started with electronics or designing more advanced circuits, understanding the 220 Ohm resistor’s characteristics, typical applications, and best practices can help you design more reliable and efficient systems.

Characteristics of a 220 Ohm Resistor

A resistor with a value of 220 Ohms restricts the current in a circuit according to Ohm’s Law: V = IR, where V is voltage, I is current, and R is resistance.

For example, with a 5V supply, a 220 Ohm resistor will allow approximately 22.7 mA of current to pass through. This is a suitable current level for driving many LEDs or interfacing with logic-level components.

Key specs to consider:

Resistance: 220 Ohms (±1% for metal film, ±5% for carbon film)

Power rating: Commonly 1/4W, 1/2W, or 1W, depending on the use case

Tolerance: Defines how much the actual resistance can vary from the stated value

Common Applications

1. LED Current Limiting: The most frequent use of a 220 omega resistor is as a current-limiting resistor in LED circuits. LEDs typically require 10–30 mA of current. Using a 220 Ohm resistor helps prevent overcurrent that can burn out the LED, especially when powered by 5V sources like microcontrollers.

2. Microcontroller Interfaces: When interfacing LEDs or switches with microcontrollers (e.g., Arduino, Raspberry Pi, ESP32), 220 Ohm resistors are used to control current flow and protect I/O pins from excessive current draw.

3. Pull-down or Pull-up Resistors: While 220 Ohms is lower than typical pull-up/down resistor values, in high-speed or low-resistance applications, it can be used to ensure strong logic-level signals or to reduce signal noise.

4. Audio and Signal Circuits: In audio applications, 220 Ohm resistors can be used for impedance matching, signal attenuation, or current limiting in op-amp circuits.

Design Tips

1. Always Consider Power Rating: Use the formula P = I²R to ensure your resistor can handle the power it dissipates. For a 220 Ohm resistor carrying 25 mA, the power dissipated is about 0.14W—so a 1/4W resistor would be adequate, but higher wattage may be needed for safety or prolonged use.

2. Check Tolerance Based on Application: For precise analog circuits, opt for resistors with 1% or better tolerance. For general-purpose applications like LED limiting, 5% tolerance is usually acceptable.

3. Combine for Custom Values: Need a value close to but not exactly 220 Ohms? You can combine resistors in series or parallel. For example, two 110 Ohm resistors in series give 220 Ohms.

4. Mind the Temperature Coefficient: If your circuit operates in varying temperatures, choose resistors with low temperature coefficients to maintain stable resistance.

Conclusion

The 220 Ohm resistor is a simple yet indispensable tool in electronics. Whether you're lighting up an LED or protecting your microcontroller, understanding when and how to use it can elevate your circuit design. Keep it in your toolkit—it’s a small component with big impact.

What are the main communication protocols in embedded systems?

Embedded systems rely on various communication protocols to enable efficient data transfer between components, microcontrollers, sensors, and external devices. These protocols can be broadly categorized into serial, parallel, wired, and wireless communication protocols.

UART (Universal Asynchronous Receiver-Transmitter) – A widely used serial communication protocol that facilitates full-duplex data exchange between embedded devices. It requires minimal hardware and is commonly used in debugging and low-speed data transfer applications.

SPI (Serial Peripheral Interface) – A high-speed, full-duplex protocol used for short-distance communication between a microcontroller and peripherals such as sensors, displays, and memory devices. It follows a master-slave architecture and is widely used in real-time embedded applications.

I2C (Inter-Integrated Circuit) – A multi-slave, half-duplex serial communication protocol designed for communication between multiple ICs using only two wires: SDA (data line) and SCL (clock line). It is highly efficient for low-speed applications and is commonly used in sensor integration.

CAN (Controller Area Network) – A robust, message-based protocol widely used in automotive and industrial applications. CAN allows multiple nodes to communicate efficiently without requiring a host computer. It ensures data integrity using error detection and correction mechanisms.

Ethernet – A widely adopted wired communication protocol that enables high-speed data transfer in embedded applications, especially in industrial automation and IoT systems. It supports networking capabilities for remote monitoring and control.

Bluetooth & Wi-Fi – These wireless protocols are essential for modern embedded systems, enabling connectivity in consumer electronics, IoT devices, and smart home applications. Bluetooth is preferred for short-range, low-power communication, while Wi-Fi offers high-speed data exchange over long distances.

Understanding these protocols is crucial for designing efficient embedded solutions. If you want to gain hands-on experience and expertise in these protocols, consider enrolling in an embedded system certification course.

Performance optimization method of integrated servo motor

1.Definition and characteristics of integrated servo motor The integrated servo motor has an integrated servo driver inside, which can directly receive signals from the controller and perform corresponding actions. Compared with traditional split servo motors, integrated servo motors reduce the number of external connection components, reduce the complexity and cost of the system. In addition, due to the integrated design, integrated servo motors also have advantages in performance, such as higher precision and faster response speed.

2.Basic working principle of integrated servo motor When the integrated servo motor receives a pulse, it will rotate the angle corresponding to the pulse to achieve displacement. Since the integrated servo motor itself has the function of sending pulses, each rotation angle will send a corresponding number of pulses, so that the system can know how many pulses are sent to the servo motor and how many pulses are received back, so as to accurately control the rotation of the motor and achieve precise positioning with an accuracy of 0.001mm.

3.Structure of integrated servo motor 1.Stator: The stator is mainly made of laminated silicon steel sheets and is used to fix the magnetic field of the motor. The stator is the stationary part of the motor. After the winding is energized, a rotating magnetic field is generated to provide a power source for the operation of the motor. ‌2.Rotor: The rotor is usually composed of permanent magnets or electromagnets and is the rotating part of the motor. In permanent magnet servo motors, the rotor has built-in permanent magnets and can generate a magnetic field without external power supply. The rotor begins to rotate under the action of the rotating magnetic field generated by the stator, converting electrical energy into mechanical energy to drive the load to operate. ‌3.Encoder: The encoder is used to monitor the position and speed of the motor in real time and feed this information back to the control system to form a closed-loop control. Common encoders are photoelectric encoders and magnetic encoders. The encoder is a key component for achieving high-precision control of integrated servo motors. ‌4.Bearings and end covers: The bearings are used to support the rotation of the rotor to reduce friction and wear; the end covers are used to seal the inside of the motor to prevent dust and moisture from entering. These components together ensure the stable operation and long life of the motor. ‌5.Controller: The controller is the core component of the integrated servo motor and is mainly responsible for controlling the speed, position and other parameters of the motor. The controller usually uses a digital signal processor (DSP) or a microcontroller (MCU) chip, which has the characteristics of high-speed computing and high-precision control. 6.Driver: The driver is the power source of the integrated servo motor and is mainly responsible for converting the motor's control signal into a motor drive signal. Drivers usually use power semiconductor devices such as MOSFET, IGBT, etc., which have the characteristics of high efficiency and high reliability. 7.Sensor: The sensor is mainly used to detect the position, speed, acceleration and other parameters of the motor, and feed this information back to the controller and driver. Common sensors include encoders, Hall elements, potentiometers, etc.

4.Performance optimization method of integrated servo motor 1.Motor selection and parameter adjustment: Select a suitable servo motor according to actual needs to avoid waste or insufficiency caused by excessive or insufficient power. Adjust the motor's inductance, resistance, rotor inertia and other parameters to improve the motor's response speed and accuracy. 2.Optimize the transmission system: Reduce friction and inertia loss in the transmission chain, use low-friction transmission devices and efficient transmission ratios, and significantly improve transmission efficiency. Redesign the mechanical structure, reduce the inertia of components, or optimize the mechanical motion trajectory to reduce the load and thus increase the motor speed. 3.Application of advanced control algorithms: The use of advanced control algorithms, such as vector control, direct torque control, fuzzy control, neural network control, etc., can greatly improve the control accuracy and response speed of the servo motor. 4.Regular inspection and maintenance: Regularly inspect and maintain the integrated servo motor, including cleaning, lubrication, tightening, etc., to ensure that the motor is in good operating condition. Once a motor fault or abnormality is found, it should be handled in time to avoid the expansion of the fault and cause greater damage to the motor. 5.Power supply stability: The integrated servo motor has high requirements on the quality of the power supply, and the power supply voltage fluctuation will directly affect the speed control accuracy and response speed of the motor. Therefore, it is necessary to ensure that the power supply voltage is stable within the rated range, and the power supply waveform can be trimmed by adding filtering circuits. 6.Heat dissipation optimization: In the process of improving the performance of the integrated servo motor, pay attention to the heat dissipation of the motor. By improving the heat dissipation design, such as adding heat sinks, using fans or liquid cooling systems, etc., ensure that the motor will not affect performance due to overheating when running at high speed. 7.Feedback system debugging: It is very important to ensure the accuracy and stability of the encoder or sensor. Perform calibration and inspections regularly to ensure the accuracy of the feedback system and handle any abnormalities promptly. ‌8.Advanced debugging tips: Use vibration analysis tools to identify mechanical vibration problems and reduce vibration and resonance by adjusting and balancing the components of the transmission system.

Week 3 Lab (2/6) Blink

The goal of this lab is to understand how Digital Outputs work and how to create them. using Arduino hardware. By constructing a simple circuit and uploading pre-created code via the Arduino IDE, we will control an LED to blink at a set interval.

Description of Circuit and Creation:

This circuit consists of an LED connected to a digital pin on the Arduino, along with a 220 Ohm resistor to limit current flow and prevent damage to the LED. The Arduino sends a HIGH (5V) signal to turn the LED on and a LOW (0V) signal to turn it off, creating a blinking effect.

The long leg (anode) of the LED is connected to digital pin 13 on the Arduino.

The short leg (cathode) of the LED is connected to one end of a 220Ω resistor.

The other end of the resistor is connected to GND (ground) on the Arduino.

The Arduino is powered via USB or an external power supply.

Explaining the Code:

Observations:

After uploading the code to the Arduino Uno, the LED started blinking on and off at a 1-second interval, confirming the correct operation of digital outputs.

Increasing or decreasing the delay() values changed the speed of the blinking.

If the LED did not blink, checking wiring connections and ensuring the resistor was properly placed helped troubleshoot the issue.

This experiment demonstrates how digital signals work, where an Arduino can control an LED using simple HIGH/LOW commands.

Q&A

The Arduino IDE (Integrated Development Environment) is the software used to write, compile, and upload code to an Arduino microcontroller. It allows a simple interface for programming and testing electronic projects paired with Arduino hardware.

2. What is a Digital Input?

A Digital Input is a signal received by the Arduino that can be either HIGH (1) or LOW (0). Examples include buttons, sensors, and switches that provide ON/OFF signals.

3. What is a Digital Output?

A Digital Output is a signal sent from the Arduino to control external components, such as LEDs, buzzers, and motors. In this experiment, the LED is controlled using digitalWrite() to turn it ON or OFF.

4. What are Microcontroller Pins?

Microcontroller Pins are physical connection points on an Arduino board that allow it to interact with sensors, actuators, and other devices. They can be input pins (reading data) or output pins (sending signals).

5. What does pinMode() do?

The pinMode() function sets up an Arduino pin as INPUT or OUTPUT. In this lab, pinMode(ledPin, OUTPUT); tells the Arduino to use pin 13 to send signals to the LED.

6. What does digitalWrite() do?

The digitalWrite() function sends a HIGH (5V) or LOW (0V) signal to a digital pin. In this experiment, it controls the LED's ON/OFF states.

7. What does delay() do?

The delay() function pauses the execution of the code for a specific amount of time, measured in milliseconds. In this experiment, delay(1000); causes a 1-second delay between turning the LED ON and OFF.

Challenges/Trouble-Shooting:

The only challenge I faced during this lab was my adapter was not the correct kind to transfer the software into the hardware in order to make the LED work properly. This was fixed by changing the adapter used to connect the Arduino board to the hardware.

In conclusion, this project successfully demonstrated how to use digital outputs in Arduino to control an LED. By setting up a simple circuit and writing code, we learned how to use pinMode() to configure pins, digitalWrite() to send signals, and delay() to control timing.This helped me understand how microcontrollers interact with physical components.
