In this tutorial, I made an LED backlight test tool obtained from used goods. Where the tools and materials are:
1. 2 transformers
2. 1 diode bridge
3. 1 set of multimeter probes
The way to make/assemble it is very easy, and this tool also has an auto volt which can adjust the voltage on the LED and this tool also doesn't cause an electric shock when touched by a finger.
