In this project a radio controlled clock with a special presentation form of the time is build. The received time is displayed on a led-matrix with six separte fields. Every field represent a digit of a digital clock. The value of the digit is displayed via the number of illuminated leds in the field.
Witch LED in a field is illuminated is choosen randomly every time the digit changes.
- µController: ATMega with 8MHz
- 45 high efficiency SMD LEDs in 5 colors
- radio controlled by DCF
- supply current 50..200mA
