This project seems to have been popular a few years ago, so it was a lot of work hunting down the code to get this running. I have set up a voltage divider circuit using almost 1 megaohm resistors (they are chunky). The only issue is that I get a burst of values, which would be hard for playing som…

Makey Makey on Leonardo - Rapid fire keystrokes

The Makey Makey doesn't use analog inputs. It uses 22 MOhm pull-up resistors and counts the number of '1' bits in the last 24 samples (about 60 samples per second). Default threshold is 55% (13 samples ON).
