Chapter 6.3 - Interfacing LM324 Comparator IC with IR(Infra Red Light) Sensor and 8051 Microcontroller on Bread Board - Circuit Diagram

Interfacing LM324 Comparator IC with IR(Infra Red Light) Sensor and 8051 Microcontroller on Bread Board - Circuit Diagram

Now as you can see in the above circuit diagram, The circuit diagram is almost same as given in the last chapter, but wait, the IR LED and Photodiode is connected with a difference. Open this subchapter in the one window and the practical tutorial in other window. And tally the circuit diagram with the breadboard connections.
