infrared emitter and detector using ic 74ls14

Posted on Feb 5, 2014

This circuit have applied to line detection of robot project, Good match between the transmitter and the detector is important for proper operation, especially if the hole is large. Robot with a simple object or obstacle detection. Infrared Transmitter detector pair sensors are relatively easy to implement, although involved some degree of testing

and calibration in order to make correct. They can for the impediment, motion detection, transmitters, encoders are used, and the color detection. This can be done with a piece of rope stretched between and in accordance with LED and phototransistor. A length of stiff wire or plugs can be used to set the alignment. Another method that can be used for long distances is a laser pointer shone through a hole.
