I made this a while back for a close friends Burning Seed costume. Today I pulled out the bulky Arduino Mega that used to drive the hat and inserted a tiny NodeMCU / ESP8266 to do a much better job! I have also installed my latest LED animations and driver software.
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.
