AVR LED Candle

February 29, 2012 By: admin Category: AVR, LED, Miscellaneous, Project No Comments →

This LED candle is built to mimic the look of a traditional candle without the dangers associated with an open flame. It uses high brightness LED and is controlled by ATtiny85. It could be useful as movie props where you cannot afford to have a candle go out during a take or in your home […]

Aurora RGB LED Art

October 27, 2011 By: admin Category: Display, LED, Miscellaneous, PIC, Project No Comments →

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.
