one section of my origin story is the self hatred i perpetrated after i found out my focused friends got internships at northrop grumman in high school. they only had three spots for students going into engineering. i was intelligent and extremely straight edge so i could get into university for free. but i also spent most of my high school experience figuring out whos house id be sleeping at , going to the beach, getting in fights on field hockey turf because i was very angry all the time, and hiding in the yearbook room listening to grimes and bjork with the other non theatre queers using indesign for our lil art and literary magazines. no one in there was concerned with math or engineering and i was switching between so many loops i was never in one fully. it was an outdoor campus as most schools in southern california tend to be. sprawling and tucked into the canyons. we had a normal quad for white kids and popular black kids, an asian quad for the non brown asians, and the senior lot where all the rich kids hung out on the roofs of their range rovers - the latinos were near the cherry blossoms that never bloomed and everyone else huddled into their respective enclaves across campus. i didnt realize NG manufactured bombs and drones until i complained to my mother than i missed the application deadline and she reminded me san diego is the epicenter of the military industrial complex, have i learned nothing from her over the years (she worked on nuclear weapons out of college before ending up in la and dating the laker). i kept studying engineering stuff in hs and that got me my scholarship (less females in engineering, higher probability of college admission and scholarship, easier to study architecture) but i immediately tweaked upon arriving in ny, first stop was canal st to get both nipples pierced, i was finally free from my household in san diego and could do as i wished. i immediately plummeted into depression, was high all the time, got the boys to do my engineering homework for me, unsure how they did it because they were all addicted to blow, weed and xanax. my gpa suffered but i did just enough to not get my scholarship revoked. i was a huge brat with admissions, i begged them to let me take any art or reading classes, they said no, this is engineering. i got the drugs and infatuation with the city and myself out of my system but all professors were doing their research and i didnt care enough to go to office hours and maneuver the language barrier to learn physics better. it took me three years to switch out of engineering because i felt like a failure once again and overthink everything especially my image to my family, although come to find out, they literally did not care because i went free. still, all indian girls are suppose to be engineers doctors pharmacists with the occassional polisci major if you come from a wealthy family and plan on law school. i fucked off to london and milan instead , enrolled in a class at csm and modeled lol but i returned to finish my degree six months later, and silo’d myself to making installations with msp and arduino and debris i found around jay street metrotech. i missed my high school reunion but i heard theres an olympic size swimming pool now Lmao

Raspberry Pi 5 / RP1 chip support for Neopixels with Python bindings coming soon 🎉💡🖥️🌈🐍

Hot off the PIO-presses, our resident Jepler created a Python binding for the Raspberry Pi 5 that lets us use the RP1 chip

on the 5/500 series boards to drive Neopixels using PIO. This is great because we can now use Neopixels

and friends on the latest Pi boards, and we can use any pin because PIO is not limited by underlying peripherals. You do need the latest kernel and firmware, so it is not quite ready for prime-time, but once piolib

is more readily available, we'll be able to have folks test this out.

SERVO DISTANCE INDICATOR USING ARDUINO UNO

INTRODUCTION

Distance measurement is a fundamental concept in various fields, including robotics, automation, and security systems. One common and efficient way to by emitting sound waves and calculating the time it takes for the waves to reflect back from an object, allowing accurate measurement of distance without physical contact.

In this project, we will use an HC-SR04 Ultrasonic Sensor in conjunction with an Arduino microcontroller to measure the distance between the sensor and an object. The sensor emits ultrasonic waves and measures the time it takes for the waves to return after reflecting off the object. By using the speed of sound and the time measured, the distance is calculated. This simple yet powerful setup can be applied in a variety of real-world applications such as obstacle detection in robots, parking assistance systems, and automatic door operations.

WORKING PRINCIPLE

1. Servo Movement: The servo motor rotates to different angles (0° to 180°). The ultrasonic sensor is mounted on top of the servo and moves with it.

2. Distance Measurement: At each position, the ultrasonic sensor sends out an ultrasonic pulse and waits for the echo to return after hitting an object. The Arduino records the time taken for the echo to return.

3. Distance Calculation: The Arduino calculates the distance to the object based on the time recorded and the speed of sound (0.0343 cm/µs).

4. Servo as Indicator: The servo motor's position provides a physical indication of the direction of the detected object. As the servo moves across a range of Image map out objects in different directions based on distance.

5. Visual Output: The Arduino can also send the distance and angle data to the serial monitor, creating a real-time visual representation of the detected object positions.

APPLICATIONS

1. Autonomous Robots and Vehicles

2. Radar Systems

3. Parking Assistance

4. Security Systems

5. Environmental Scanning in Drones

6. Warehouse Management and Automation

7. Industrial Automation

8. Robotic Arm Guidance

9. Collision Avoidance in UAVs/Robots

10.Interactive Displays or Art Installations

11.Smart Doors and Gates

CONCLUSION

The Servo Distance Indicator Project successfully demonstrates the integration of an ultrasonic sensor and a servo motor to create an effective distance measurement an object, the project provides real-time feedback through the movement of a servo motor, which indicates the measured distance via a visual representation.

Arduino Due vs. Mega: A Comprehensive Comparison

What is Arduino Due and Mega?

The Arduino platform has revolutionized the world of DIY electronics, providing hobbyists and professionals alike with versatile and powerful microcontroller boards. Among the myriad of options, the Arduino Due and Arduino Mega stand out for their advanced features and robust performance. The Arduino Due, introduced in 2012, is the first Arduino board based on a 32-bit ARM core microcontroller, the Atmel SAM3X8E. In contrast, the Arduino Mega, built around the 8-bit ATmega2560 microcontroller, is known for its abundant I/O pins and memory. Understanding the differences between these two boards can help in selecting the right one for specific projects, enhancing both functionality and efficiency.

Processing Power and Performance

The processing capabilities of the Arduino Due and Mega are distinctly different, primarily due to their core microcontrollers. The Arduino Due, with its 32-bit ARM Cortex-M3 processor running at 84 MHz, offers significantly higher processing power compared to the Arduino Mega's 8-bit ATmega2560, which operates at 16 MHz. This difference in architecture and clock speed means that the Due can handle more complex calculations and tasks faster and more efficiently than the Mega. For projects requiring high computational power, such as real-time data processing or handling multiple sensors simultaneously, the Due is the superior choice. However, for simpler tasks, the Mega's processing power may suffice.

Memory and Storage Capabilities

Memory is another critical aspect where the Arduino Due and Mega diverge. The Arduino Due is equipped with 512 KB of flash memory for code storage and 96 KB of SRAM for data. On the other hand, the Arduino Mega has 256 KB of flash memory and 8 KB of SRAM. Additionally, the Due features a Direct Memory Access (DMA) controller, which allows for efficient memory operations, freeing up the CPU to handle other tasks. These memory enhancements make the Due more suitable for applications requiring large codebases and significant data handling, such as advanced robotics or sophisticated control systems. The Mega, with its more modest memory, is ideal for less demanding applications.

Input/Output Capabilities and Expansion

Both the Arduino Due and Mega are renowned for their extensive input/output (I/O) capabilities, yet they cater to different needs. The Mega boasts a whopping 54 digital I/O pins, 16 analog inputs, and 4 UARTs, making it ideal for projects that require multiple sensors, actuators, or communication interfaces. The Due, while offering fewer digital I/O pins at 54, includes 12 analog inputs and 4 UARTs, along with additional features like two DAC outputs for analog signal generation and enhanced PWM capabilities. These features provide the Due with superior analog output capabilities, making it suitable for applications like audio processing or advanced signal generation.

Power Consumption and Compatibility

Power consumption and compatibility are practical considerations when choosing between the Arduino Due and Mega. The Due operates at 3.3V logic levels, which makes it more power-efficient than the Mega, which uses 5V logic levels. This lower voltage operation is beneficial for battery-powered projects where energy efficiency is crucial. However, the 3.3V logic also means that the Due is not directly compatible with 5V components without level shifters. The Mega, with its 5V logic, offers broader compatibility with existing Arduino shields and components, making it a versatile choice for a wide range of projects. Understanding these power and compatibility nuances can help in making an informed decision based on the project's specific requirements.

Thanks for the tag, @a-fox-studies! I don’t really know that many codeblrs, so I’m leaving this as an open tag for others.

At what point in your life did you decide that the world of computers was the one for you?

I wanted to make games long before I knew what it takes to make one. All I knew is that I enjoyed games, and that I wanted to make something enjoyable too. So I guess, from the start, I was going to get hooked to computers one way or another. Knowing past me, though, I would not have gone this path if I found programming too hard, so the incremental steps I was given was a factor.

Back in 8th grade, we had to take C++ in our computer subject. It was just a general computer subject but it was nothing like I had taken in earlier years. We didn’t glance at any of the STL aside from strings and iostream (for stdin/stdout), so it was really enjoyable for me. Plus, we were spared from pointers because we didn’t have enough time for the school year to discuss any of those.

The next year, I was invited by our teacher to join the robotics team. We didn’t do well, but I liked that time of my studies. We went to numerous seminars, all of which I enjoyed (especially that time where we controlled a robot with our phones; that was a blast making it roam all around the room). I tried to make a piezo electric speaker sing, but I didn’t like how the piezo sounded, so I stopped after a few notes. We tried to make an RFID reader work for a competition. It worked in practice but, without changing anything in our setup, failed during presentation. Thankfully, it wasn’t an on-stage presentation, so only the judges (and the teams beside us) saw us trying to figure out why our working code wasn’t working.

I tried C# on my own time. I asked our computer teacher about the programming language we use for the Arduino and he said “C#”. In hindsight, he probably didn’t know as well, but thought that it looked similar to C#. It challenged me, which was my main motivation for learning. However, it wasn’t too hard that I dropped it. My previous experience with C (C++ implies STL) meant that I knew the syntax. My experience with Arduino meant that strange problems weren’t that strange to me anymore. Plus, using Visual Studio made it easy for me to transfer my idea to code.

From then on, I knew that I wanted to pursue this path. I continued learning C#, explored other languages, and made some of my own packages, modules, and applications. I have yet to create a game of my own, but that will come when I can finally force myself to make sprite assets.
