My original multimeter failed me. It wasn’t either the battery or the fuse so I revisited Radio Shack and $21 later, I got a new one.
The drum pad just houses a trigger.
So I wired a drum pad and a drum pedal to a 9v battery and attempted to measure the voltage:
The pad seems to vary in voltage when it’s hit. It doesn’t fluctuate when it’s not hit. I’m quite willing to accept that wiring up a 9v battery is less than ideal here but it’s indicative of the fact I *will* need the ADC.
The drum pedal really acts as a switch so an ADC isn’t required here.
