I'm just starting to play with some long 24" FSR's with an Arduino. The tutorials I have read so far show that there is a 10k fixed resistor as a voltage divider. The tutorials only show this for one FSR, though.
Let's say I have 12 FSR's. In this case, I'd be using the 24" long FSR's in a diagonally staggered arrangement as step sensors connected to one analog input since any sensed step would all trigger the same effect.
Would I need multiple resistors (1 for each FSR) or just one 10k resistor at the top of the row of FSR's with wire connecting each one to each other?
I might be making this more difficult than it needs to be.
