Chapter 5.1 - Interfacing LM324 Comparator IC with LDR(Light Depended Resistor) Sensor on Bread Board - Description


In this Chapter we are going to Use LDR (Light Dependent Resistor) Sensor and Interface it with LM324 Comparator IC. The basic concepts are breifly explained in videos in the previous sub chapter. We hope that you have learned about the potential divider circuit and LDR. In this chapter we will try to make a small circuit where if the path of LDR is obstructed, then the light connected to LM324 Ic will glow and indicate. When the path will be clear, then the LED will turn off. So gear up and start up with the next sub Chapter.
