This robotic musician uses miniature solenoids to tap out melodies on a toy xylophone. The Adafruit Grand Central M4 controls each of the eight solenoids using CircuitPython, one of the fastest growing programming languages, specifically designed to simplify experimenting and learning.

We found a cute little robot on thingiverse that used a simple, yet clever locomotion system. Simple in that it used a single yellow (dual shaft) TT motor to control both sides, with the addition of only a battery and power switch.
The basic design is, as I said, clever. What could be done to expand on it? We could use two motors. A CRICKIT would provide finer, individual control of the motors. Using the Feather M0 Bluefruit with the Featherwing CRICKIT would let us drive it remotely. All this additional hardware will require the robot to be larger. Check out the full guide!
A bumper car is usually driven by a crazed carnival-goer — but we’re going to build a self-driving Bumper Bot! This bot will use the Circuit Playground Express for brains and collision detection with its onboard accelerometer. The Crickit will provide all the muscle needed to drive two TT DC gearbox motors, as well as a micro servo direction indicator flag.
A small speaker and NeoPixels will also give us feedback while to bumper bot is out there having fun!! Check out the full guide!
This project guides you through building a robot that can wander around your floor. This riffs on John Park’s Crickit Carnival Bumper Bot. The difference is that the project progresses through several levels, starting with a very basic bot and adding capabilities. Check out the full guide!

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.
