hey guys, im interested in a little experiment involving the 50mm softpot. i have all the components listed here: https://www.sparkfun.com/products/10174
including: multiple capacitors, AD420ANZ DAC, 78L12A 3 terminal regulator and LM358N op amps.

Has anyone done a project using the softpot? Im interested in either:
A piano playing different tones as different spots are touched on softpot
OR
varying LED brightness depending on area touched on softpot.
If anyone has done one of these or knows how, some circuitry diagrams/code tips would be really appreciated. Thanks!

I have a 100m softpot, it behaves exactly the same as a rotary or slider potentiometer. Connect outer pins to power and ground, middle pin to an analog pin on your board and use analogRead() to get a value between 0 and 1023.

Look at my thread on the faux buttons I made with a softpot: http://arduino.cc/forum/index.php/topic,110955.msg834913.html
