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.
