LED Multiplexing Arduino Code

This is an awesome Arduino project. Print any alphabet & animate using multiplexing.

The Main purpose of this project is to demonstrate how to extend the digital pins of an Arduino using shift resistors.


We need:

  1. 6 x 1k Resistors
  2. 2x 74CH595 Shift Resistors
  3. 1 PCB
  4. Arduin UNO
  5. 16 Pin female headers
  6. 36 LEDs
  7. Wires
