Hi all, My name is Dexter, I am 15 years of age and this is my first instructable. It will show you the inside of the USB cable. And will show you how to connect a light to it. NOTE: Do not directly connect an LED to a USB cable, use a resistor. I appologise for the poor quality of the photos.
Step 1: Strip one end of the USB cable
Strip an end of the USB cable, remember to leave a USB port on one end, show the wires inside (with their coloured covers). The wires should be the same as in the photo below, the red wire = 5 Volts (+) and the black wire is the ground (-), for now ignore the other two wires I will hopefully make an instructable about them at a later stage. We will only use the black and red wires for now.
Step 2: Connecting the light
OK firstly, I don't exactly know the type of light I use here, if you do please email me at email@example.com . Connect the negative(-) wire of your light to the ground (black) wire of the USB cable and the positive (+) wire of the light to the red (5 volts) wire of the USB. Once the wires are connected nicely go to the next step.
Step 3: LET THERE BE LIGHT!
Connect your USB cable into your USB port and the light should shine like in the photo below.
That concludes this tutorial. Hope this helps you in any way and that you have enjoyed my first Instructable.
