/*
 * To measure the muscle flex of the forearm, from a flex sensor that is connected to an Arduino.
 * This muscle flex sensor 'MyoWare' measures the filtered and rectified electrical activity of a muscle.
 * Gets the electrical activity of a muscle and produces an analogue output signal that can be read by the Arduino.
