This project and its circuit are one of the most basic and popular sensor modules. In electronics, this sensor is analogous to human’s visionary senses which can be used to detect an obstacle which is one of its common applications. In robotics, a group of such modules are used so that a robot can follow a line pattern.
This circuit is made using the following:
1. LM358 IC 2.
IR Transmitter and Receiver Pair
3. Resistors of the range of Kilo ohms
4. Variable Resistors
