Sometimes, when we need to learn how to do something, we create a project out of it. This was one of those times, and what we wanted to learn was to control a bunch of individually controllable LEDs with Fadecandy and make it react to Facebook events.
We are huge fans of parametric design, and we wanted to explore this in the project. We ended up with a large grid of 8×64 LEDs in a pattern where every LED is in the center of virtual hexagons. Above ~200 of these LEDs we would 3D-print thin, hollow and transparent hexagonal columns in different heights. The height and position of these columns would be designed parametically. Above the remaining ~312 LEDs we would glue on cotton the diffuse the light and give it a “cloud look”.

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.
