Homemade LED light tester DIY, Simple LED tester and LED voltage tester.

These Inductors are available in SMPS Power supply boards, AMPS boards, and TV boards ( LED, LCD ) .

This is a very good simple circuit and you can apply an LED tester circuit and an LED voltage tester. Can 3.7v to 5v DC supply. this is a Boost circuit. the maximum output voltage is 32V.

Components used in this project:–

1. Irfz44n MOSFET
2. 220 Ohm / 2w Resistor
3. 220uf/25V Capacitor
4. Testing Probes
5. Volte meter
6. Inductor
