I'm working on 1-pixel pacman on a 64x32 LED matrix using an Arduino Mega. I also have a 32x16 LED matrix and an Arduino Uno and would like to use them to continuously draw the player's score to the 32x16 as the game progresses. I'm new to Arduino so I've been researching about serial communication…
