Aurora RGB LED Art

admin — Thu, 27 Oct 2011 01:16:08 +0000

Aurora 9×18 is a beautiful firing sequence of 162 RGB-LEDs in a circular configuration. The color of each circle is controlled by a microcontroller (PIC24F08KA101) using a twisted form of PWM. The MCU only has one PWM module, yet Aurora is capable of 27 (9xR,G,B) independent brightness control.The project uses an idea of combining [...]
