Simply the machine has four types of candies and each type has it’s special code, you should tweet with this special code to get your candy.
Actually we participated with this project at Bay Area Maker Faire last week and I intend to continue my last journey to inspire kids to use modern technologies to create their own toys instead of wasting a lot of time in playing with smart phones or PCs.
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.
