NIGHT LAMP WITH LDR & LED

In this project we are going to show you how to control LED with the help of LDR(Light Dependent resistor). It shows how LED gets on Automatically in Darkness. So let’s do it

Working :

LDR is the device whose resistance depends on light. In this project we are going to show you how LDR works. When light falls on LDR does not pass the current and own LED gets off and in absence of light LDR becomes active and passes the current So LED glows.

Step : 1

Take LED, LDR, Battery and Connecting wires

Step : 2

Connect the Positive terminal of Battery with LDR

Step :3

Connect another terminal of LDR with positive terminal of LED

Step :4

Connect negative terminal of Battery with negative terminal of LED Your Night Lamp is Ready. It will glow as u put finger on LDR
