My friend and I are trying to connect a simple Force Sensor Resistor to our Arduino. All we have is the FSR itself, the Arduino, and a couple of wires and resistors. What we eventually want to be able to do is, drop a coin on to the sensor and then output the weight of the coin on a separate screen.
How does the wiring go? I am completely new to Arduino and have no idea.
Vin is +5v from arduino, Vout goes to a analog input. R1 or R2 is your sensor, the other one should be a resistor with about the same maximum resistance as your sensor has (I think ... not sure right off the top of my head - but the wiki page should have the formula which should help you figure it out.)
