LM324 Photodiode sensor or Infrared Proximity Sensor (Line following Robots’ Sensor)
Hi friends!!!!
Today we will talk about LM324 IC or Infrared Proximity 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 LM324 Photodiode sensor Or Infrared Proximity Sensor.
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
