[About Aurora 9x18]
Using
162 LEDs, Aurora 9x18 creates beautiful waves of colors. The heart of
the unit is PIC24F08KA101 micro-controller. Using a proprietary
technique, this controller controls 9 x 3 (RGB) independent channels of
PWM signals. The result is just beautiful.
The unit is a little over 4 inches in diameter. Fitting all of the components in this small unit was no simple task.
