The term Bluetooth comes from King Harald “Bluetooth” Gormsson, a man who is known for uniting Denmark and Norway and had a dead tooth which earned him his name. Though we’re not looking for you to connect countries, we do want you to connect wirelessly for the Bluetooth Challenge!

Bluetooth is all about sharing data over a short distance without using any wires. Find a way to cut the cords and bring your projects to the wireless age for a chance to win a MacBook Air! Don’t get bogged down by cables and go wireless with everything Bluetooth.

The Bluetooth Challenge is closed.
