Dr. Megan Smith and I [krazatchu] have cooked up a circuit board to control Christmas lights. It’s Arduino compatible, based on the Mega328 and has a microphone, audio line in and a light sensor. It can switch 7 strings of lights with the ULN2003 transistor array. It also has Infrared for communications, to work with a TV remote or to talk among themselves to coordinate lighting events (I’ll be using some code from my firefly project: http://www.lumipendant.com/).
We will be giving workshops to assemble and program these controllers early December at ArtsCourt, Ottawa, Ontario Canada. The first application will blink a morse code Christmas message. We have named the project: “Hack UR Baubles”.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
