Use a Raspberry Pi and a Pi Camera Module to build your own machine learning–powered rock paper scissors game!
Here’s why you should always leave comments on our blog: this project from Julien de la Bruère-Terreault instantly had our attention when he shared it on our recent Android Things post.
Julien and his son were building a text-based version of rock paper scissors in Python when his son asked him: “Could you make a rock paper scissors game that uses the camera to detect hand gestures?” Obviously, Julien really had no choice but to accept the challenge.
“The game uses a Raspberry Pi computer and Raspberry Pi Camera Module installed on a 3D-printed support with LED strips to achieve consistent images,” Julien explains in the tutorial for the build. “The pictures taken by the camera are processed and fed to an image classifier that determines whether the gesture corresponds to ‘Rock’, ‘Paper’, or ‘Scissors’ gestures.”

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.
