I made a calibration program using Arduino that uses serial to make the arduino choose to do calibration or read values.
The calibration fixed problems caused by error between actual output voltage and expected output voltage.
Calibration is a step in the right direction.
However, improvements need to be made to the calibration program to fix sensing multiple bends.
The assumption that only 3 individual sections need to be calibrated since multiple bends are just a linear combination of the values of 3 individual sections is not working very well.
The program needs to spend more time finding the max value output when a complete bend is made.
