Mimicking robotic arm that mimics a user's finger movements via flex sensors on a glove using the Arduino Mega and pwm. We set up an auto-mapping feature to map the servos to an open and closed hand. One of the most difficult parts was the filtering. We ended up using both hardware and software filters. We used an active low-pass filter and a programmed averager to get the final noise reduction. We then used some cardboard that was lying around to mock up a hand to drive the servos.
