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 whole thing worked because of all the generous people who have written Arduino code, and also code to adapt the basic Arduino stuff to work with alternative chips from the Microchip was Atmel) AVR ...

Arduino pins. Here, we are using 3 pins to drive 3 2 − 3 = 6 LEDs. Note that, we setting related pins (D5-D6-D7) of the Arduino to one of the three states (tri-state logic): HIGH (H): 5V LOW (L): 0V ...

In the Leonardo, an op-amp between the ATmega pin and the led means that loading is minimal and the pin can easily be used as an Arduino input. This buffer is missing on the Micro, which means even ...
