I made this fun Ikea Lantern mod that projects lighted flying birds. It’s an Arduino project using FastLED and FadeLED and my custom code. The hardware is Neopixels with bird cut outs in projector boxes. I used a vinyl cutter to make the boxes. And there is about 5 sticks of hot glue to hold it all together. Total cost is less than $100.
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.
