Osu keypad (3 keys)

# 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.
