USB Output Checker

This is a very simple project. There are no efforts to make this.

This is useful in two ways:-

1. This is a lightning product if you put white light then it is helpful to show laptop keyboard in dark room.

2. I made it for as "USB Output Checker" Because you can't check the female USB Hub is giving current or not by multi-meter.

Step 1: Component Required

To make this project you need these:-

Male USB

100-160ohm Resistor

LEDS (As needed) (max. 4)

Soldering Iron

Soldering Stand

Soldering Paste

Solder

Step 2: Circuit Diagram

This is the circuit diagram of this USB output checker

Step 3: Finishing and Done! ;)

Attach these components like the picture . and solder it by Soldering Iron.

You may add up to 4 LEDs in series for more light but in case of USB Output Checker 1 LED is efficient.

Step 4: Demo!!

Enjoy Your Light........
