If you like LED display project here is another cool project : Arduino based POV globe. This persistence of vision project able to displaying monocolour bitmaps up to 72 pixels high and x width. (uses 72 LEDs, and one input to get rotation speed). The main component in this project is atmega328P, 72 SMD [...]
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 said [...]
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.
The Electronic Mini-Badge project is a PIC24FJ64GA004-based electronic badge that displays color slideshows. Many electronic badges display scrolling text using a matrix of discrete LEDs. This low-power system features a graphical OLED display and can be easily upgraded to handle animation, video, or RF communication.
The PIC24FJ64GA004 microcontroller is used as a compromise between the speed [...]
