This project shows how to send SMS text messages to a cheap scrolling LED display via an Android app and arduino with USB host shield.
The project was originally inspired by a friend wanting to make a "sexting themed" costume, with a scrolling LED display of live texts sent from people at the party. We found a $13 LED belt buckle online, which looked cool, but only had a few buttons to manually enter in messages. A couple wires and lines of arduino code later, we were able to automate entry of messages.
We then added a host shield and wrote a small Android app to send txt messages on to the arduino.
