Abstract

The purpose of this project was to develop a scrolling LED sign with an embedded system capable of wirelessly interfacing with the Twitter social networking service. The embedded system is built on an ASUS wireless router running a specialized version of Linux. Python code running on the router downloads information through the Twitter API and updates the sign over an RS-232 serial interface. The sign is configured over local network via a web browser by accessing the system’s PHP-enabled web server. Authenticated access is achieved by connecting to a third-party server that requests access from Twitter. The final product supports a variety of configurable operating modes.
