Operation Amplifier

An Operation Amplifier can be used to get a stronger and more stable signal from a resistive sensor.

Breadboard View

Use a 10K pull-down resistor, any resistive sensor (an FSR for example) and an LM 358 Dual Op-amp. Connect the parts as shown in the screen-shot and also feel free to place a small ceramic cap between PIN1 on the Opamp and GND to smooth the signal even better.
