First of all, I would say, English is not my mother tongue; so please excuse any errors on my part.
In addition to usage as normal LED display, the “INTERACTIVE RGB LED TABLE” is like a “touch screen” made of LEDs with impressive animations. It is used as a dinner table, coffee table, decorated table in a bar, or living room table…. For the project I share below, this interactive LED table is sized in A2 with 256 RGB LEDs, uses infrared emitter and photo-transistor to locate the object on the table and create a nice effect at the corresponding position.”
