TBH I'm still inclined towards contacts or resistance / voltage, simply
because to me they're a known quantity and I think will help to get
this project finished ASAP. Other methods are just fine and I'll sample
some 16F193x to investigate the mTouch for future reference, perhaps
even swapping it for whatever goes into the project to get it going
