Led Matrix With AT90S2313 Microcontroller Circuit LED ball physically assembled in a matrix of dimension 20 Rays and 7 LEDs. LEDs are governed microcontroller and two decoder K155ID10. Operating current 80mA decoders, this is enough to connect the LED matrix in the dynamics of directly between the microcontroller and decoders, excluding transistors, the brightness of [...]

This project flashes 18 LEDs at three different rates and you can use these to create a Christmas decoration of your choice. The circuit is kept simple (and cheap!) by using the 4060B IC which is a counter and oscillator (clock) in one package. The circuit requires a 9V supply, such as a PP3 battery. [...]
