We are experiencing problems with the generation of values in the serial monitor.
We have connected an Arduino Nano and a FSR to a breadboard. We referred to this tutorial and followed their setup and code. https://www.instructables.com/id/Interfacing-Force-Sensitive-Resistor-to-Arduino/.
With no pressure exerted, the values generated are more than 0, and fluctuate at around 200-400. Sometimes, the values drop to 0, but immediately go up.
We already confirmed that our Arduino Nano is working fine with the Blink test, and used different computers to run the code, and used different FSR sensors, and tried different circuit designs, but we keep facing the same issue and we do not know why.
Does anyone have a solution to this issue? Thank you!
