Force Sensitive Resistor Hookup Guide

Resources and Going Further

Now that you've got a force-sensing Arduino circuit, what project are you going to create? If you need more FSR-related resources, be sure to check out the integration guide/user manual, which goes in-depth on the sensor's characteristics. The guide also presents a few more complex circuits you can try hooking up to get even more sensitivity out of your FSR. Try making a pressure-sensing button or adding some feedback to a robot gripper.
