How to make an automatic cabinet/ wardrobe light

This project will show you how to make an automatic cabinet/wardrobe light that uses only one battery. This circuit has a very long battery life and easy to install, it does not consume any energy when standby too.

All parts you need:
1 x 5 volts led strip
1 x 18650 battery
1 x refrigerator door switch
Soldering iron
hot glue gun

18650 battery can supply around 3.7 volts but the 5 volts strip can operate without any problem.
This automatic cabinet light doesn't consume any energy when standby because of the switch is just on/off switch that uses metal contact.

Let's see how it works in the video below.
