Cheap_USB_LED_Light_For_Computer

When I see USB contest I was thinking about USB LED light which I wanted already to do in the past. So now I made LED light. Always when I must open my computer and look for some number, add or remove some component, or else, I looking for some light. And when I find flash light, the battery doesn't working, then I searching for battery, of course I don't find any good one. Lets start building USB LED Light.


First what we need of parts;

- USB Cable
- Two white LED 
- One 220Ohm resistor
- Some protective thin tubes

Step 1 Prepare_LED_Diodes

Now we must solder together LED diodes. Diode have A - anode [+] and K - cathode [-]. We must solder together anodes and cathodes.
