Component list:
- 27 LEDS
- 9 220 ohm Resistors
- Arduino
- Wire (jumpers)
- 2 Protoboards
Skills required:
- Basic electronics
- How to solder
- Programming (if you want to create your owns effects, it's really easy)
Instructions
First step:
Weld all the LEDS cathodes (short wire) together.
Then make two more
Second step:
Join the 3 layers by welding all the anodes ( long wire).
Third step:
Connect each column to digital pins 5-13 with a 220 ohm resistor and each level directly to pins 2-4.
Fourth step:
Upload the code (http://www.megaupload.com/?d=5UNQF384)
Fifth step:
Enjoy (:
