Night Light Automatic On Off System using LDR | Automatic Street Light Circuit

In this video i will show you how to make a automatic night light on off circuit using ldr. This circuit can sense the light and drive the relay depending  on light. This circuit is very useful for night light, street light etc. We need the following components for making this circuit:
- Light Dependent Resistor (LDR)
- 100K Potentiometer
- 10K Resistor
- 1K Resistor
- 3mm Led

- LM358 OP AMP IC
-  BC547 Transistor
- 1N4007 Diode
- 5V Relay
- Terminal Block
- 5V Power Supply
