Kid's Game to Arduino Enigma Machine

Step 3 Figure Out the Keyboard

I pulled the rubber buttons off the keypad PCB so I could figure out how it was all wired up. To figure out how it's wired up a used a multimeter on the Ohm meter setting to test for continuity. I put one lead on the row of pins on the cable the came off the keyboard to the "brains" of the game, and the other on the bare metal on the button circuit board for each button. I just used a sheet of paper to keep track of what button went to what pins.

That's all there is to it
