Linking Max/MSP and the Arduino board wasn’t too hard thanks to the Max plugin ‘Maxduino‘

All we have done so far is control 2 outputs (Pin 12 and 13) and used a single input with a switch, hooked up to our Max/MSP sequencer file. We put a counter on to count the amount of bangs the button was producing, and came across a problem. The button was not adding 1 each time, it was adding random amounts, sometimes up to 20 at a time. After about half an hour of confusion, it was discovered that the wires on the switch were not connected problem, hence the large numbers being output. Doh! Here are some pics:
