A 4 and 6 Button macro pad that use an arduino Pro Micro as the controller an your flavor of cherry mx/gateron style switches

To wire the switches up to an arduino Pro Micro wire a common ground wire to a single pin of every switch and then run one wire per switch to a pin on the arduino.

To code it use the arduino IDE and this guide https://www.sparkfun.com/tutorials/337
