Tomorrowland is the largest electronic music festival held in the world. It’s held in Boom, Belgium and is known for its extensive decorations and impressive shows. The aftermovie of this year’s edition (2014) should give you a pretty good idea of the atmosphere at the festival.
At this year’s edition the paper entrance tickets were replaced by electronic bracelets. Every guest got a pretty box in the mail containing their personal bracelet. On the inside of the bracelet a unique ID (UID) is lasered onto the leather strap. The guest has to register this number on the website of the event to link the bracelet to his name and ticket. At the event an RFID scanner is then used to scan the bracelet and grant the guest access to the festival site.
But the bracelet had a couple more functions. The leather band clearly has 2 RGB LEDs embedded on either side of the watch face. These LEDs are remote controlled by the FOH to light up in sync and with the correct color to match the light show. This is a pretty neat effect, especially when a couple thousand people are waving their hands in the air.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
