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 work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

The listed vender sells it separately for $32 and it brings all its pins out to 1.27mm headers and has more functions than the Arduino adapter brings out. the module at a quick glance seems to ...

In principle, Charlieplexing technique allows you to drive “n 2 −n” LEDs using only “n” Arduino pins. Here, we are using 3 pins to drive 3 2 − 3 = 6 LEDs. Note that, we setting related pins (D5-D6-D7) ...

It transpires that folk have been busy writing ‘cores’ – the name for code that adapts Arduino code to run on different hardware – for several other bare chips, and some have 20 pins – plenty. Have ...

The Arduino-compatible shield is highly compatible and allows you to mount and power a Raspberry Pi Zero or the new Zero W mini PC and communicate with an Arduino-compatible micro-controller via ...
