Changing resistors
The dome buttons are lit by a LED set up for 12V DC. Replaced resistors in each LED with a 100 ohm resistor so now can use 5 VDC (30mA per pin) - would be better if it were 20mA but had 100 ohm resistors and arduino can source up to 40 mA per output pin.

Whack A Mole Dome
Inspired by Sparkfun and their Whack A Dome I started a smaller version with only 9 buttons. Using their code as a start, here goes
Start of the prototype. Counter display is from Adafruit and will be controlled by Arduino Leonardo
