For a previous project I explored what it would take to create a text marquee on an 8×8 LED matrix display without microcontroller, using only 7400 chips, an old EEPROM and breadboard components. Matrix Displays I was interested in using an LED matrix display and I picked up some cheap 8×8 ones on Amazon. medium.com That worked, but 8×8 is very small to do anything interesting and so I wanted to give it another go, create a larger 16×16 panel, design a custom PCB and ultimately hook it up to a microcontroller this time to write some games for it.
