Populate the ledPins array with the list of Arduino analog output pins the strands are connected to (the strand's positive wires). The pins don't have to be in sequence like the example shown there.

This project enables individual control of an array of 8 LEDs using an Arduino Uno. Each LED is connected to a separate digital pin on the Arduino, allowing for versatile light patterns and displays.

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.

The term “Charileplexing” is not a familiar one for many electronics hobbyists. Charlieplexing is a technique proposed in early 1995 by Charlie Allen (at Maxim Integrated) for driving a multiplexed ...
