A small bag my mother and I have made for a 4 year old girl (called Theresa) with sewable electronics. It has 4 neopixels (some kind of RGB leds) controlled by an Adafruit Gemma. It is powered by a lithium battery. If the button at the top is pressed shortly, the leds start blinking in random colors for 100 s and then turn off again. If the button is pressed longer, the leds turn on till the button is pressed again in colors corresponding to the crocheted flowers
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.
