Tom’s RGB mood lamp

Tom’s RGB mood lamp
The module consists of a Atmega8 microcontroller. It uses PWM to control 3 different LED’s found in a RGB Led. Because it uses PWM to control the 3 colours we can also control the brightness of the colours. This allows us to create various colours using the three original colors (Red,Green and Blue).[more]

Fading RGB LED PWM

Fading RGB LED PWM
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]

brain machine

brain machine
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]
