^ That could probably work too. I haven't dug into the code yet, but I don't see any reason why the buttons would be hardwired to those pins, other than that's how it's best laid out on the MPGuino device PCB (I'm having to make some of those odd trace-influenced design/code decisions on my own project ATM).
Curious though. How do you think you could blow out a diode by wiring signals together? o.O Seems very strange. Only way I could think of blowing out a diode is by hammering it with a high reverse-polarity voltage, or putting too much power through it...
