How to Make a Ridiculously Cheap Analog Pressure Sensor

Step 4 Test

That’s it.  At this point, test it on your multimeter, if you have one.  You should see a nice range of resistance depending on how hard you are pressing or not.  If necessary, you may want to hook up a resistor with this depending on your usage.

Hi

These would be easy to hook up to an arduino, right? What would I need to do in the system to pick up the resistance change on the circuit?

Cheers

You could build these into a potential divider to get a change in voltage as an analogue input. Or you could build a Wheatstone bridge to find the unknown resistance.

Seems like you could make drum pads.  But I think using piezo elements is a better way.  Look up todbot and his tutorial on "Spooky Arduino".  There are also other sources using a microprocessor and piezo element for a drum-like instrument.

I suggest placing the foam between two squares of thin pcb to which the wires are soldered.

so with these, I could make my own drum pads for something like rockband or guitar hero, or am I way off?
