This project involves using a Raspberry Pi to drive 8 AC outlets which are connected to Christmas Tree light sets. The AC lights are simple one color strands of lights, but to give a more dynamic range to the light show there is also a 25 programmable RGB LED star. One of the benefits of using the Raspberry Pi instead of an Arduino controller is that I can drive the audio out of the Raspberry Pi to have the lights timed with music (not to mention the benefit having a WiFi connection to work on the software remotely).
12mm Diffused Thin Digital RGB LED Pixels (Strand of 25) – WS2801: RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each RGB LED and controller chip is molded into a ‘dot’ of silicone. The dots are weatherproof and rugged. There are four flanges molded in so that you can ‘push’ them into a 12mm drill hole in any material up to 1.5mm/0.06″ thick. They’re typically used to make outdoor signs. Read more.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
