Raspberry Pi LED Controller Build

[IdeaMakers]

Hi All, received the Raspberry Pi board along with the WiPi USB Wireless Network adapter and power supply. Here's a photo of the beginning pieces:



So what's the plan, well I'd like to connect non adressable RGB LEDs to the board and be able to change / program the colors more then most of the shelve controllers can do. This all started last fall when I hooked up some simple white LEDs under the eves of our garage so the light floods down the wall. Also having done work on energy conservation (and being the son of depression era parents) anytime I can save a little juice I'm into it. In the case of the garage I went from a single 60 watt incandescent bulb to roughly 8.5 watts of LEDs that produce a lot more light. I liked the lighted wall look enough to try and do the same on the front of the house only with RGB LEDs.

Here's a few links to the current setup I'm using:

12 Volt Power Supply (clipped the plug off to hard wire to the household wiring)

The RGB Controller is the piece I'd like to replace with the Raspberry Pi. The controller is very basic in that you can adjust brightness and colors but it won't remember the changes from one night to the next and there is no way program the color changes, just shades of RGB. I'd like to have red, white and blue for the 4th and purple, orange and strobes for Halloween and not wanting to spend $250 for the fancy controller I thought I'd give it a try and maybe learn something along the way.

So here's what I'd like to see in my controller:
Connect via WiFi to change colors
Be able to load in scripts for different schemes
Come on at night and off during the day
Make it so easy my wife can use it
Remote control from Ipad app
Database of holiday lighting schemes (probably unnecessary but cool)

So I have the basics and now on to build the rest. David was helpful (patient) the other evening in explaining MOSFETs and transistors as well as mixing the 5v Pi with the 12v LEDs. So here's the next piece to the puzzle:

Bread Board (really starting at the beginning here)
N-channel MOSFETs
Adafruit 16-Channel 12-bit PWM/Servo Driver – I2C interface
Pi Plate or Cobbler
Light sensor

If there are any suggestions out there I'd love to hear them. Until the next update, John
