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.

This is mini sound level monitor project. It will display fluctuating light bars as response of audio signal from Electret Microphone. The louder sound that come into this device, the brighter the light bar. This project use alkaline battery as power source.
The ‘brains’ of this project is a LM358 general-purpose op-amp. The front part of [...]

If you like electronic project related to LED display then Ceiling Fan LED Display worth to try. It is persistence of vision project by unclebone. Instead using common motor for POV, he used Ceiling Fan as moving part. Because it run at the right speed and very quiet compared with alternatives. To control the LED [...]
