LM324 Photo diode sensor Or Infrared Proximity Sensor (Line following Robots’ Sensor)
Line follower robot needs sensors to detect the line to follow. Robot can detect line in two ways. One is using vision sensor (Robotic eye) or using Photo diode sensors as the line is drawn in single surface with two differentiating colors. Robotic eyes are too expensive so we will have to use use photo diode sensors.
Now we are going to build a sensor that will sense the reflective objects from a certain distance. This will work as proximity sensor. The Continue reading “LM324 Photo diode sensor Or Infrared Proximity Sensor”
