Enter the ExtraCore library for Arduino, a software library that turns two or more Arduinos into a multi-core microcontroller with more pins than you’ll ever need.

PWM pins are generally used in controlling output devices in Arduino projects. To send a PWM value to a PWM-capable pin like the Mega's D9, the easiest and most common way is by using the ...

Arduino-compatible ATtinys with more pins Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Further, the voltage output (VOUT) pin can be directly connected to the ADC input of a microcontroller. (pin annotation of the linear active thermistor chip) Although the 3-pin SOT-23 package of ...

Developers, hobbyists, Arduino or Raspberry Pi enthusiasts looking to combine both Raspberry Pi and Arduino systems in the same project may be interested in a new shield for Arduino created by ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Ar… ...

You can use these pins with your projects. The Arduino Nixie Tube SHIELD is now available to back via indigo go with pledges starting from $25 and shipping expected to take place during December 2017.
