Boomstick is a project for creating an animated string of programmable RGB LEDs, powered by a small Arduino, and reactive to music. This guide focuses on one hardware configuration that you can assemble in order to run the Boomstick software. This hardware is a great size for putting into a wearable item such as a robe or spirit hood, or lighting up the length of a portable totem pole. The components include a mic (to pick up music), a knob (to adjust brightness) and a button (to switch animations). The whole unit (including LEDs) is powered from a single micro USB port, which can be plugged into a wall adapter, or a portable USB battery charger.
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.
