What is it?

Android phone controlling LED lights.

Tell me more

Google has supported interfacing with the Arduino for many years. My goal was to see how feasible and easy would it be to use a Google Nexus phone to control an LED light strip. I’ve used a fairly cheap strip with a lame controller (PD6803). It’s important to note that the easiest way to make it happen was to use the Arduino ADK board. It allows “out of the box” interfacing with the Android platform. A native Android app listened to the system events such as incoming SMS or phone calls. The event triggered an Arduino method with a parameter (1=SMS, 2=Call) which resulted in pre-programmed LED shows. Simple, right?
