A fancy Santa hat with added NeoPixel strip in the band, NeoPixels in a custom designed 3D printed bobble that also hides a rotary encoder to change the sequence of the band when turned one way and the bobble when turned the other. Microcontroller is the Adafruit Gemma wearable micro, powered by a small lipo battery, both hidden in the band.
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.
