How to Build a Simple Force Sensing Resistor (FSR) Circuit

In this article, we will go over how to connect a force sensing resistor, or force sensitive resistor, (FSR) to a circuit to build many different types of useful circuits with them. Force sensing resistors are variable resistors which change resistance according to the pressure or force applied to them. Under no force, the resistance is very high, pretty much infinite. When a light pressure is applied to th ...
