Osu keypad (3 keys)

myminifactory

A simple osu keypad with 3 mechanical keys using an arduino pro micro. Clip in place the mechanical switches (MX style) Solder one pin of each switch to ground and the other to its own pin (2,3,4 is the default). Make sure you don't short the board. Secure the arduino and close the lid Adit the arduino sketch to match your key pins at the top, change the key codes to your liking, compile it and flash to the board via arduino IDE. Add keycaps and have fun ! You can also optionally add 3 leds, one for each switch and modify the sketch to match the pins you used. Just make sure your led comes from a free pin and goes to ground.
