The lights in the Aurora consist of a grid of 544 RGB LEDs capable of ~16 million colors attached to a 4’ by 8’ wood board. The LEDs are controlled by a microcontroller, which is in turn controlled by a program running on a laptop. The computer is the brain of the system, being responsible for creating the graphics that appear on the wall, and the microcontroller relays the messages to the LEDs. The PC software connects to software running on an iPad, which allows interaction with the moving patterns. Also, the Aurora has a mode where the builtin programs respond to music, bouncing and flashing with the beat, turning it into a VJ of sorts.

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.
