USB led light

Step 1: Materials

USB plug and cord
Blue LED (any other color will work too)
100 ohm resistor
Case or housing to hold the led ( I used a cheap mini keychain flashlight housing)

Tools Needed to do this project

Soldering iron
Screwdriver to take apart case

Step 2: Assembly

Open keychain flashlight housing and remove all components. Solder positive wire of USB plug to the positive of the LED, solder the negative lead to the 100 ohm resistor, and solder the other end of the resistor to the negative of the LED. Install components in case.

Step 3: Test It

Connect to a working USB port and it should light up. :)
