How to interface Force Sensitive Resistor to LabVIEW using Arduino Uno?

Hi everyone

I am newbie to LabVIEW. I want to interface the FSR(force sensitive resistor) to LabVIEW using LIFA(LabVIEW Interface for Arduino) to display the force in Newton. pls help me.I need a comple vi program

thanks in advance

Any resistance-based sensor will simply use an analog input voltage with Arduino.  So, you need to have an electrical circuit that will output a voltage that varies with the resistance of your sensor.  Then, it's just a matter of converting that voltage to a standard unit of measure with a conversion formula.

So, hook it up like you would for any other Arduino project (I found a tutorial here but skip the Arduino code part).  Then, simply read the analog voltage with LIFA.  The formula needed to convert from voltage to force will depend on your particular sensor and the resistor that you use in your circuit.

If you are still having issues then please provide more details about your setup and the exact sensor that you are using.
