If you had a Teddy Ruxpin in the ’80s and ’90s, you probably remember inserting special tapes and hearing him read stories to you. Whether you loved or hated the little bear, it was hard to forget his weirdly moving mouth and eyes. Today though, with small and cheap development boards readily available, this mechanical system is just begging for a retrofit.
In this project, hacker “Tinkernut” employed an Arduino to sense the intensity of a sound input, and in turn used it to allow Ruxpin to lip sync to any audio source. This could be a song, story, or even output from a virtual assistant.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
