Project: Automatic Street Light

Automatic Street Light

Let’s make a small circuit through which we can understand the working of a light sensor.

Component Required :

The components required for this project are:

  • Power-1

  • LDR-1

  • Power Junction-1

  • NOT Gate -1

  • LED-1

  • Gray Plate -1

  • CT2-10

  • Power Bank -1

  • USB to DC jack -1

Circuit Connection :

Now let’s start with the circuit part. 

  • Take the power block 

  • Add a light sensor and NOT gate to the Power block.

  • Let’s start with the circuit. 

  • Take a power block and Join a Light sensor to it.

  • Add a NOT gate to it.

  • Lastly add a Bright LED at the end. 

  • Power the circuit with Power bank and USB to DC jack. 

  • Turn on the power supply. 

Now when the sun goes down i.e., when the light around the Light sensor gets dimmer, the LED will start glowing. Similarly, during sunrise the light around the light sensor increases. Hence the glow of LED also decreases.Â
