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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
