Automatic Night Light Penstand || DIY

Introduction: Automatic Night Light Penstand || DIY

Here, I am going to show you how to make a Night Sensing Penstand which glows ON automatically at night or in darkness.

This project is based on Dark Sensor Circuit, which is a circuit which turns ON the load (lights) when it detects darkness. The key component for making this project is LDR - Light Dependent Resistor, a photoresistor whose resistance varies with the change in the light intensity that falls upon it.

Step 1: Material Required

To make this project, we require:

LDR – Light Dependent Resistor

Transistor – BC 547

Resistor – 47K Ω

• LEDs (4)

• Switch

• Battery (9V) and Battery Clip

• Wires

• PCB

• Cardboard

• Paper

Major Tools required:

• Soldering Iron and Solder Wire

• Hot Glue Gun

Step 2: Circuit Diagram

This circuit is basically Dark Sensor Circuit
