Osu keypad (3 keys)

thingiverse

# 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.
