I have exhausted my searching abilities. I would like to make a score board for 2 teams that just increments the score up from 0-21 with the push of a button for each team. I have follwed a guide that originates here Arduino Scoreboard by TrevisanGMW - Thingiverse however when putting in this code I get all the max7219 leds lit up at the same time. (I have loaded other text scrolling codes to verify my wiring and understanding is correct) I have loaded the libraries and followed a wiring diagram so I'm assuming its in the code. If I can't get help thats ok I will continue trying somehow.
