Myoware

Hi
I am doing my thesis with myoware to collect signals from the thigh muscles. I extracted the signals from the vastus lateralis and semitendinosus (thigh muscles). However, I am not able to pick up the EMG signals from the rectus femoris. I tried collecting the signals with different myoware and adjusting the gain.

A power of 5V is given to the myoware via the Arduino board
