This project uses two Raspberry Pi’s, communicating over WiFi using XMLRPC, along with an Inertial Measurement Unit (IMU) sensor and a Maestro Servo Controller to have a 3-axis skull wirelessly mimic the head movements of the operator, who is wearing a baseball cap with the sensor Pi and IMU unit mounted on the brim. (A shoutout to Greg G on Haunt Forum for the ball cap mount idea).
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.
