Step 2Receiver with RGB-LED
The Receiver is based on the atmel avr169 demoboard named butterfly. The board have a lot of features not used in this project. The wireless tranceiver is connected to PortB and the pwm-controlled led is connected to PortD. Power is supplied at the ISP-header, 4.5V is enough. The wireless board can tolerate 5V on i/o pins, but need 3.3V supply which is supplied by the onboard regulator.
The modified header-cable for the rf tranceiver is really convenient, and connects wireless board with power and hardware spi controller on the butterfly.
The shiftbright is a rgb-led pulse width modulation controller which accepts a 4 byte command which is latched in and then latched out on the output pins. Really easy to connect in series. Just shift out many command words, and the first shifted out will end up in the last connected LED in the daisy-chain.
