PieterP:
It is.An expression pedal is just a potentiometer, you can connect it to the Arduino like you normally would (left pin = sleeve to ground, wiper = tip to analog input, right pin = ring to Vcc).

Perfect! Thanks for the help Pieter! I was reading that article earlier and appreciate them sharing the info.
Somewhat of a side note, should the arduino/my desktop usb port be able to handle half a dozen leds, the board, the expression pedal power wise? I was hoping to only have a single (micro usb) cable running to the board? (I plan on trying to check the current usage on a DMM when all my parts arrive)
Any guidance is much appreciated, thanks again
