New Arduino Key Lib can Read 6 Buttons using only 3 I/O pins

Postby wholder » Thu Aug 03, 2017 4:30 pm

I've written a new key input library that supports a special type of multiplexing that can scan 6 buttons using only 3 I/O pins, 10 buttons using 4 I/O pins, 15 buttons using 5 I/O pins, and so on. For more details, see my web page and video at:
