What is a Microcontroller?

A microcontroller is a self-contained system with peripherals, memory and a processor that can be used as an embedded system. Most programmable microcontrollers that are used today are embedded in other consumer products or machinery including phones, peripherals, automobiles and household appliances for computer systems. Due to that, another name for a microcontroller is "embedded controller." Some embedded systems are more sophisticated, while others have minimal requirements for memory and programming length and a low software complexity. Input and output devices include solenoids, LCD displays, relays, switches and sensors for data like humidity, temperature or light level, amongst others.

Types of Microcontrollers

There are several different kinds of programmable microcontrollers at Future Electronics. We stock many of the most common types categorized by several parameters including Bits, Flash size, RAM size, number of input/output lines, packaging type, supply voltage and speed. Our parametric filters will allow you to refine your search results according to the required specifications.

Programmable microcontrollers contain general purpose input/output pins. The number of these pins varies depending on the microcontroller. They can be configured to an input or an output state by software. When configured to an input state, these pins can be used to read external signals or sensors. When they are configured to the output state, they can drive external devices like LED displays and motors.

Raspberry Pi Alternatives – 17 competitors

Raspberry Pi has become the next big thing.

Both Raspberry Pi and Raspberry Pi 2 have created great, intense interest in single-board computers.

Simple portable, and affordable, they bring a lot to the table.

However, maybe you don’t want a Pi. You might be looking for something that fulfills the same functions but is a bit different. There are a lot of alternatives to Raspberry Pi out there.

First, let’s look at what makes the Raspberry Pi unique and some of the reason you might want to look for a Raspberry Pit alternative. The Raspberry Pi Model B boasts a 900 MHz processor, a full HDMI port, 1 GB of RAM, a camera interface, a display interface, a micro SD card slot, and a GPU. It can run both Windows 10 and Linux. All this will run you around $35.

You can still pick up the first gen Raspberry Pi, but it has noticeably worse specs than the Raspberry Pi 2. The original has a 700 MHz processor, either 256 or 512 RAM, and only either one or two USB ports. A few of the very earliest models do not even have Ethernet ports, so there’s no alternative to using Wi-Fi. The Raspberry Pi 2 is a clear improvement.

All these seem like serious selling points for the Raspberry Pi, but there are issues. A lot of computers like Raspberry Pi provide more power, with faster processors, better GPUs, more RAM, and more connectors. They can even offer services no model of Raspberry Pi offers right now.

You can find that some of the Raspberry Pi competitors offer features like built in Wi-Fi, gigabit Ethernet, and occasionally a decent amount of onboard storage. The barest, most stripped down version of a computer can work for a lot of people, but you’ll find it has a lot of limits, especially for complex projects.

Arduino Industrial 101

Arduino Industrial 101 is an Evaluation board for the Arduino 101 LGA module. It supports Linux distribution, which is based on an OpenWRT named LininoOS. The ATmega32u4 microcontroller is fully integrated in the baseboard.

This computer’s board has built in Wi-Fi, utilizing IEEE 802.11b/g/n operations up to 150Mbps 1×1 2.4 GHz), 4 Analog inputs, 1 USB, 3 GPIOs (2 of which can be used as PWM Outputs), and 1 Ethernet signal on pin header. It also has a built in DC/DC converter. Use the assembly guide, then simply connect your board to a computer using a micro USB cable to get going.

Please note that in some countries, it is against the law to sell Wi-FI enabled devices without government permission. Some local distributors disable Wi-Fi functionality while awaiting certification.

Banana Pi

Meant to be an open source, Banana Pi is touted as a close alternative to Raspberry Pi. It is manufactured in Chine and is noticeably, but not very, physically larger than the Raspberry Pi. It has assorted OS options available, including Lubuntu, Fedora, Arch Linux, Free BSD, a Debian variant named Bananian, Android 4.2, and Android 4.4.

You can use the Raspbian OS, but the CPU will compile it with all the requirements of the Debian Armhf port.

The hardware offers up a lot of similarities to Raspberry Pi. There are several variants to the Banan Pi boards, but these are the specs on the most current one, the Banana Pi M64: a 1.2 Ghz Quad-Core ARM Cortex A53 64-Bit Processor, 2GB of RAM, and 8GB eMMC.

It comes with built in Wi-Fi and Bluetooth. There are 2 USB A 2.0 ports, a USB OTG port, an HDMI port, an audio jack, and a Dc power port. A few models also offer SATA 2.0 port support. It’s truly standout feature is its storage capacity. You can use an SD card with a max of 64 GB, and get a max of 2 TB via the SATA port.

The versatile board makes this a good choice for anyone who wants to try building their own computers. It’s not as cheap as some Raspberry Pi competitors, but it is hardly expensive.

BBC micro:bit

This tiny computer is meant for schools. More than a million of them were given away to school children in the UK. They’ve since started to be handed out globally. A non-profit named Micro Bit Educational Foundation now manages this effort.

The BBC micro:bit is powered by a 32-bit ARM Cortex. It has a 5x% LED matrix, with 25 programmable red LEDs for a display. There are a few push buttons allowing for interactions for games and other programs. It also has a Magnetometer, Accelerometer, and Bluetooth antenna.

What is Arduino? A Brief Observe the Arduino Platform

Desktop PC

Arduino is an open-source, programmable microcontroller and software program primarily based on the ATMega chip. Despite the fact that the Arduino is designed as a prototyping platform, It can be utilized in diverse electronics Initiatives whether brief or embedded. The Arduino board can be programmed the usage of the Arduino software. The syntax for that is similar to C/C++ and Java. It’s miles designed to be easy and easy to apply and can be operated with the aid of all people, from beginners to professionals alike.

As Arduino is an open supply platform, You could get preserve of the supply code and schematics for it. This indicates You could delve as ways into it as you want, even growing your own Arduino boards. There may be additionally a massive network at the back of it, and You can discover many tutorials and Initiatives from all around the global on line.

What can I do with an Arduino?

Quite much something you need! It has been utilized in such a lot of one of a kind approaches as the options are really unlimited. Beyond Projects have covered robots, artwork installations, in-car computer systems, MIDI controllers, cocktail makers, human-Laptop interfaces, Fb ‘like�� counters, advertising shows, clocks, tune tool, custom mouse and keyboard, domestic automation… The list goes on and on!

The primary capabilities of an Arduino board are its capacity to study data from sensors, to ship and acquire Virtual alerts and might connect through serial for your Computer. You may control much stuff, from LEDs and LCDs to automobiles and relays. You can also examine values from sensors together with potentiometers, mildly structured resistors (LDRs) and piezo.

The Digital pins on an Arduino can help you study or write 5v values. You can use a pin to turn on an LED (with a resistor). You can send a sign to a relay to function higher voltage home equipment like televisions and house lighting. You could ship messages to automobiles to show on and off. You may test to peer if a button has been pressed. You can even send and receive serial records, parallel information, and Virtual pulse width modulation. Essentially something that may be controlled via a bit of modern can be used.

The analog pins let you examine an incoming voltage between 0v and 5v. This will be the way you read from sensors. There is a mess of sensors available, from simple hands-on pressure sensors and rotary potentiometers to surroundings sensors together with stress, fuel, temperature or even alcohol. If you have, as an example, a slider set to exactly half of its range, it has to output a voltage of 2.5v. The Arduino can then read this and use the price to control something else.

You do not forestall with just controlling digital circuits. You could send statistics again to the Pc to manipulate software program which includes Processing and Max/MSP. You can send the records over USB with most models. some fashions have Bluetooth and Ethernet ports, and with additional shields (like an upload on the unit) You may communicate via WiFi and other protocols.

What cannot I do with one?

Bit meaning

The Arduino does not have lots of processing strength, so Pretty plenty any principal extensive mission is out of the query. You might not be capable of procedure, report or output video or audio (Although You can output pictures to TFT or Liquid crystal display screens). It is not like a Pc. You may not be capable of hook up your webcam or keyboard to it. There’s no operating system with a GUI (like a Raspberry Pi). It’s miles a completely unique beast.
