Hello all,
I'm working on a robotic hand that mimics the user's movement. I am trying to use SE-08606 flex resistors (as a voltage divider) with an Arduino to detect finger curling into a fist. My problem is that there is a lot of noise and the servos that curl the fingers become really jittery. I'm thinking that I could use a low pass filter to get rid of the noise (my thought process is it will filter out the noise into a smooth movement of the servos). I put the circuit below with the filter I was trying to use (which doesn't work). Do you think there is any low pass that would work for this? Or if I'm even approaching this noise reduction issue properly?
Much appreciated
