Arduino / Raspberry Pi Keypad by telboy2002

Ever get fed up with push buttons keep falling off breadboards, I re-purposed this Keypad from an old microwave. Cut all the trace links not needed and soldered all all as individual outputs with common GND. I now have up to 9 buttons plug and play.
You can adapt the 123d file for how many buttons you want on a perf board
