Ok - got this wired up on my breadboard.

I've set up an attachInterrupt to println("change") to the serial console but it's constantly sending that. Something is wrong


The output is around 2.8 to 3 volts - it goes lower (>1 or so) when I put a piece of metal in front of the VR sensor. So it seems to be working to some degree.

I'm guessing because it's not going to 5 or 0 but somewhere in between?

Got it working, had to swap the VR sensor wires. Works well now :)

Except that all of a sudden my Arduino just seems to be counting up and up rather than the number of pulses (made a simple program for testing to do this)... guessing I might have killed it somehow...?
