HBO asked us to create an interactive window experience for their retail shop in Times Square for the 2009 holidays. We built a snow blowing machine that senses people walking by on the sidewalk and launches snow into the air in response. The installation was developed with the openFrameworks programming API and the physical hardware was controlled using an Arduino. An IR sensor array detects how close pedestrians and window-gazers are, and using mechanical relays, switches on and off fans under the snow in response. A Large LED wall behind the snow is also reactive to street traffic as well. A sliced winter forest scene changes color and moves in response to street traffic.
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.
