Tangeez are a set of interactive light blocks that change color depending on how you stack them. You can get 7 different colors out of one block. They’re about the size of a cupcake and fit in the palm of your hand. They change color as you stack and rearrange them. There’s lots of fun to be had with Tangeez as you can see form the pictures here!
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.
