The circuit is very simple. The RGB LED is hooked up to the PWM outputs on PORTB1 , PORTB2 and PORTB3 of the ATMega8. There is also a resistor between the LED and the ATM8 to limit the current to 20mA. There is also a link to the datasheet of the RGB LED that is used in this project. The code for the fading LED is written in assembler with the AVR Studio 4. In this example the LEDs will fade in and out one by one. The PWM timers of the ATMega8 are used to let the LED’s fade in and out.[more]

This is an improved version of Mitch Altman’s Brain Machine.The hardware is based on an ATMega8.It uses only very few of the I/O ports: two for audio, two for LEDs, one for a pushbutton, so it should be easy to use another controller that has an 8bit timer with two PWM channels (OCxA, OCxB).Add a piece of prototyping PCB, four capacitors, two resistors, a switch, connectors for headphones and glasses, and two AA cells, and you’re done.[more]

This is an USB HID gadget, capable of converting CIR signals from a remote control to keystrokes and/or mouse movements. It uses an ATMega8 AVR microcontroller and the Objective Development firmware-only USB driver stack.The device contains a TSOP1738 infrared receiver & demodulator, which picks up the signals from the remote control. The microcontroller implements a combo HID device, simulating both a mouse and a keyboard. This way it can send mouse movements, button clicks and keystrokes (such as PageUp, PageDown, Enter, Escape, etc.) to the PC. [more]
