i want to make a custom controller to select different shower heads in my shower.
I have 3/4 solenoid valves hooked up behind each shower head but am having issues with making a professional looking waterproof interface.
I was wondering if i had a glass panel with 4 risers
set in from each corner, like this (but on a smaller scale):
if i set up the risers to push against 4 force sensitive resistors (with a spring to maintain lateral pressure when not being pressed) . would i be able to detect which area of the glass was pressed based on which resistor has the greatest change? There are only 4 buttons and they would be evenly spaced out in a 2x2 configuration (or 1x4)
this is the resistor i was thinking of getting: http://www.sparkfun.com/products/9673
