home made led and diode tester auto voltage simple and useful

Hi friends, meet again at Chanel Qimunk Creative. I hope you all are healthy amen..
This time I will create a very creative video idea that not many people know about.
And that is certainly very, very useful.
In this video I will share a useful trick, namely making an electrical tester. This circuit is one of the simplest and cheapest circuits for testing LEDs, TV backlights and diode testing.
Don't forget there is a risk of electric shock.
When using this circuit, be careful not to touch the tip of the tester cable stick because you could get an electric shock.
This circuit is just an LED tester, not a driver for LEDs
DANGER
Risk of electric shock.
And how to make it is very easy.
If friends are curious about how to make it, read and watch the video until the end. Happy Creation.
