The goal of the project is to build a self-reconfiguring LED Dot matrix display. It uses ATmega48 based modular LED matrix display unit, Kingbright TA20-11EWA LED matrix array, which can be chained together to form a self reconfiguring and arbitrary length LED matrix display. A head unit consisting of an ATmega168 is placed at [...]

This project shows you how to build simple flashing light based on IC 555. The 555 has function as clock generator with dutycyle less than 100 and more than 50. The other components are Voltage regulator, 3 power amber LED and passive component like resistor and capacitor. The project submitted by Musheg Khurshudyan. He [...]

This high power led mood light based on PIC16F628. By varying pulse width from MCU you can produce millions of color combinations using one 3 watt RGB power led. You can choose fading or jumping mode between colors.
The project features a rainbow style or a random color changing behavior. You can set a slow [...]

Led 3D-ball is 3D lights effects project based on microcontroller AVR AT90S2313 and 2 decoder 74145. The project could be use as decoration balls for Xmas and New Year trees, bars, cafes, disco and more. The matrix measuring twenty rays all over seven led. The microcontroller firmware written in basic and compiled with bascom AVR.
