An ever-changing LED display makes for an interesting show. An LED table powered by tweets makes the light show that much more exciting. This Twitter-enabled device builds on a previous project which had uses 81 RGB LED modules in a 9×9 grid arranged atop an IKEA coffee table.
The “Live Twitter Table” extends the multi-colored LED display by adding a Bluetooth Arduino Shield which wirelessly connects to a nearby MacBook Pro. The table is controlled by tweets broadcast with the #ledtable hashtag and formatted with pixel coordinates for the LED matrix. Â AÂ Twitter interface code parses the incoming Twitter posts and transmits it via Bluetooth to the Arduino microcontroller. A continuous stream of Tweets sets up the changing display on the LED table.
Macetech details the entire project from the stage of putting together an IKEA coffee table with LED grid including the source code. For your own LED project, you can try hooking up several wireless devices to a central computer and have them display your own LED designs.
