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.http://shoprollerbrights.com/. What's the point in buying them if you could make them???
Step 1: Ingredients:
- 20 DIP chip holder
- 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.
- 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
- Electrical tape
- Double-sided tape
