Arduino Force Sensitive Resistor (FSR) Tutorial | Measure Pressure & Touch
Add pressure and force sensing to your Arduino projects with a Force Sensitive Resistor (FSR). This tutorial shows you how FSRs work, how to wire them up, and how to read pressure values to trigger actions or measure force.
⚖️ What you'll learn and more things to explore:
• How FSR sensors work (resistance decreases with force)
• Wiring an FSR with a voltage divider
• Reading pressure values with analogRead()
• Calibrating and mapping FSR output
• Project ideas: pressure pads, grip monitors, smart furniture
