Introduction: 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:-
LEDS (As needed) (max. 4)
Step 2: Circuit Diagram

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.
