This project is from Extreme Electronics that describes an AVR-based (Atmega8) remotely controlled fan regulator. The control commands are received through a DVD player remote control. With three buttons on the remote control, you can turn the fan On and Off and also conotrol the speed. You can also purchase the PCB for this project too.

This project describes an automatic light system for kitchen sink where you need sufficient light to properly clean your dishes and vegetables. It uses an ATTiny84 microcontroller with a PIR motion sensor. When motion is detected, the microcontroller turns on the light. The light source consists of 10 bright white LEDs that are driven by a IRF612 MOSFET. One advantage of using a microcontroller is you can create light fade-in and fade-out effects using PWM.

This project describes an open source color game development platform based on an AVR microcontroller. You can code a color, high resolution, smooth video game, like Super Mario Bros or Commander Keen on this system. All video processing is done by software in background using interrupts, with no external active components. You only need to connect the AVR to a RGB monitor. AVRs don’t have enough RAM for direct video memory, and therefore a TILE based graphics driver is used. In TILE, the display screen is divided into X*Y tiles and each tile graphic is addressed from reference table located in
