Picture of littleBits Serial Controller

littleBits are fun little electronic modules you can use to build things. With the release of an Arduino module, you can now connect littleBits to your computer to control applications and other things running on your desktop.

In a previous Instructable I talked about getting serial data from the littleBit Arduino module. This time I'll get into using that serial data to control something.

Step 1: Get up to speed

If you haven't follow the Instructable for littleBits Serial Data, do that first. It will walk through the process of getting the Arduino code installed and running. Once that's done, you'll need to install Processing. Go to processing.org and download Processing. (It's open source/free, and very useful!)

Once you have Processing installed, you'll need some code that can read the serial data and react to it.
