How To Build A Arduino Mood Lighting

This instructable will show you who to build a rgb lighting system with an Arduino. You can also control it with an iPod/iPhone/iPad using touchOSC. In my previous instructable I showed how to control one rgb led in this you can control heaps with a single chip the ULN2003A.

Arduino mood lighting

Step 1: Parts

You will need

ULN2003A ic or equivilent
common cathode RGB LED’s(- + – -)
jumper wires
breadboard or perfboard
Resistors based on your led(I used one per channel)
Cable for linking RGB LED’s around your home(optional)

Step 2: The circuit

Red to pin 9
green to pin 10
blue to pin 11

Step 3: Program

Use the code below for your system

There are two sets of code bellow one is a simple flash red, flash green, flash blue and is my code. The other is iPod controlled with Arduino IDE and processing code it requires the oscpc5 processing library and is iPod/iPhone/iPad controlled using touchOSC.
