Hi, Can anyone see any issues connecting an Arduino directly to eight columns of an 8*8 matrix and a decade counter to the rows ?
Using the counter I can drive the eight rows from a single pin i.e.
clear column port/s clock row set column port/s repeat ...
Assume that current limiting resistors are in place and that the decade counter will drive a transistor connecting each row to ground.
I have an idea to build a chunky arcade game using LEDs, taking some inspiration from bluespirits invaders project here -
The old grandstand arcade games that I used to play as a kid -
Thanks Duane B
