If you need an easy way to control the light color of your strip lights this weekend project uses an android phone to send data to an Arduino via a USB cable. You are able to select various colors on the android device and have the LED strip instantly display what you are doing. I think using an Ethernet connected Arduino and a WiFi app would make for a great addition to this project.
“There are many ways to connect your smartphone to an embedded microcontroller. In this project you’ll use an Android phone in USB host mode. This way, the Android phone both powers and communicates with the Arduino! Even though the Arduino is connected via USB, the communication happens via serial, just like when an Arduino is connected to your computer.”
