Hall effect...

Testing out a hall effect sensor. There is a small magnet embedded in the rotating disk that the sensor reacts to when it is directly in front of the sensor causing a digital signal to be sent to the micro controller. This is used to find "home" for the stepper motor when it is powered up - a starting point for it to move on from to reach precise degrees of rotation in order to display specific numbers or letters. 84,91,47,0,B
