Rainbow Cube Kit Problem!

Hey all, I recently bought a 4x4x4 RGB LED Cube Kit, with the RainbowDuino V3.0b (AtMega 328), I built it up following the instructions and everything, but when I try to connect the USB Cable to RainbowDuino, nothing happens, Not even 1 LED would turn on, I tried downloading the example codes, and upload them to the RainbowDuino, but nothing, I get absolutely no results at all, please I need some serious help, am I doing something wrong? Thank you from advanced.

Take a look into shematic… You have to add a power source (6-12V).
Rainbowduino runs only with USB but the LED Matrix need more Power (1A) as USB can supply

Solved. Thanks

thank you…
