Giant Interactive Crossword Puzzle Uses 130 Arduinos

via Arduino Blog

In what is perhaps the most Arduino boards used together, 130 Arduino Nanos, (plus an Arduino Mega), 130 RFID readers, and 750 RGB LEDs power this interactive crossword puzzle.

As you might suspect, bringing a giant crossword puzzle to life was lot of work. If you’d like to know how much, you can see the process laid out in the video below. Like many great hacks, this project starts out with a lot of prep, making sure the mechanical pieces go together as they should. Everything is then wired and programmed, and on day six, it finally goes out the door, destined for the National Museum in Warsaw, Poland.
