Build your own animatronic eyeball using Crickit , Circuit Playground Express, a ping pong ball, two servos, and some cardboard! This new guide shows you how.
With this simple hierarchy of ping pong ball -> micro servo -> bracket -> full servo, you’ll create a two-axis gimbal that allows the eye to look in any direction!
You’ll program it with MakeCode’s simple-to-use graphical interface so that it glances around, or even puppeteer it using the accelerometer tilt built into the board!
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
