Sure, the animated eyeball that ships on the Adafruit Hallowing board is spooky…but “you wanna see something really scary?”
Move around an invisible spirit board (aka Ouija board) that can be seen only through the Hallowing’s screen. The onboard accelerometer reacts to subtle tilting to scroll about, or touch one of the capacitive fangs to have the oracle spell out a message on its own. With a little Arduino know-how you can customize the messages! Add a lanyard to make a cool Halloween fashion accessory.
There’s also an explanation of how this sort of buttery-smooth™ animation is accomplished.
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.
