HOW TO MAKE AUTOMATIC EMERGENCY LAMP

Hello Friends

In this blog  i am going to show you how to make a  automatic emergency lamp

for this we use a dark sensor circuit using LDR

Basically a darkness sensor circuit turn on a light in darkness and turn off light in brightness.



COMPONENTS

1.LDR

LDR is a  variable resistor

The resistance of a ldr decreases with increasing incident light intensity

2.transistors

2n3906,bd139

3.10k resistor

4.3.7 li.ion battery

5.tp4056 li.ion charging module

6.led strip
