Testing and Consequences

Testing

The Receiver/Sensor and Sender IR LED is placed an1/8 to a 1/4 inch apart maximum, parallel and almostcontacting.

Glow of IR LED by using the digital camera.

Measure the sensor input by DMM in ambient light &when a piece of white paper is held near to the module.

The data is taken and varied along with motor duringcalibration.
