Simple IR Emitter and Detector Module

All in one Infrared Emitter and Detector Module This module integrates 2 infrared emitting LED’s and 2 IR detectors. It works by continuously sending a 38 kHz beam of IR light from both LED’s.  As the robot approaches an obstacle, the IR light reflecting off the object will cause one or both of the detectors to send a LOW signal to the microcontroller.  This in turn will cause the robot to slow or stop one or both drive wheels depending on the level of detection.
