Gorgeous DIY Philips-Hue-Style LED lights with Node.js and Beaglebone #beagleboneblack @TXInstruments @beagleboardorg
Ben Radler posted up this great project on his site.
My roommate works for Apple, and travels to China for work. He brought back a spool of LED lights, and hacked together a script for an Arduino that played a series of 12 lights on repeat.
We then installed the lights in the ceiling in the upstairs of our apartment in San Francisco. It looked like this:
CRITERIA FOR SUCCESS
We decided we wanted to create a simple UI that could be used to pick colors. Our criteria for success were as follows:
set all banks of light a single color
set colors individually on each bank of lights
save color choices and be able to bring them back up
same UI usable on desktop, tablet, and smartphone
For the UI, I decided to base the design off of the awesome Color by hailpixel. This brilliant colorpicker interface allows you to adjust color on 3 axes:
X axis: hue
Y axis: lightness
Z axis (scrolling): saturation
Clicking allows the user to save a color into a “bank”. The color can also be adjusted after the fact. Each saved color gets added to the URL as its respective hex code.
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.
