Picture of RGB LED Skate Lights
I like to go skating every week but I noticed that the my skates weren't cool enough so I decided it was time for some lights! I installed these lights on my Dad's skates as a thank-you present for taking care of the pool for us :D. Thanks Dad!

The project is just two RGB LEDs controlled by a ATtiny2313. Very cheap and easy to make with GREAT results!

Please give it a vote for the Microcontroller and I Could Make That contest and favorite!

My project is trying to imitate these. What's the point in buying them if you could make them???

Step 1: Ingredients:

  • ATtiny2313
  • 20 DIP chip holder
  • Arduino
  • RGB common anode LEDs with appropriate resistors.
  • A diode. Really any kind of diode will work. The only purpose it has is to lower the voltage a little bit. The battery pack which is 4 AAA puts out 6 volts. The ATtiny2313 peak voltage is 5.5 so I use a diode that drops the voltage (from the battery pack) .7v just to be safe. That gives about 5.3v which is just under the ATtiny's max voltage.
  • Wires
  • Breadboard with jumpers
  • Perf board
  • 90 degree pin headers
  • Female pin headers
  • 4x AAA battery. I bought this one from Radioshack and it worked great. Usually I don't buy from Radioshack but it was cheap enough (2.99$).
  • Heat Shrink
  • Wire strippers/cutters/
  • Soldering gun and solder
  • Dremel or other device to cut perf board
  • Sharpie
  • Electrical tape
  • Double-sided tape
Last of all you will need the Arduino sketch. You can download that from here.

While I'm not going to explain how to do this in this i'ble I made a very detailed i'ble on how to program the chip. Head over to to see how to program the IC.

Really nice! Congrats!

It would be awesome if you upload a vídeo of them in action!
