I have made an LED matrix to Run Alphabets A-Z in a loop.
It was a 3x5 LED matrix and controlled by an Arduino nano programming board.
Check out the steps and also the DIY video below.
(The sponsors of the video is JLCPCB, a PCB manufacturing company, where I got my PCB design manufactured. you can find them here: www.jlcpcb.com . You may make a PCB board, or use a dot board or bread board depending on your preferences.)”
