IR remote control, voice prompts, DC motor control, NeoPixels… made with Adafruit CRICKIT (video) – more CRICKIT vids’ here (playlist) & here’s the code.

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.

  1. This is the *ultimate* use of the interwebitubes. I must stop now as my head has exploded.

    Lady Ada and PT: you will have to work very hard to top this one!

    Party on and Be Excellent To One Another!
