There are a number of Arduinome Parts Lists out there, but I figured I would do my own, more for my own recollection than anything else. I’ll probably be adding to this until I’ve completed the project. Items below are grouped by supplier.
Arduino USB Board (SparkFun)
Button Pad 4×4 – LED Compatible (SparkFun) x 4
Button Pad 4×4 – Breakout PCB (SparkFun) x 4
Unsped Arduino Shield (Unsped) (irregular availability)
More to come…
Some other parts lists out there on the interwebs:
Bricktable
Nomeist
Curious Inventor (also a nice build log)
