A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand. 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. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. 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, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. The tiled graphics approach used in the Adafruit displayio library is ideally suited for a sliding puzzle game. It is configurable so that different images can be used, and it supports both 3×3 (8 tile) and 4×4 (15 tile) puzzles. It uses pictures for the puzzle, with numbers superimposed to make the puzzles easier to solve. This is a sliding puzzle game written in CircuitPython for the Adafruit PyBadge and PyBadge LC. Basically, the tiles are randomized, and then must be returned, by sliding adjacent tiles into the open space one at a time, until the puzzle is returned to the original arrangement. The puzzles may have letters forming words or have pictures instead of, or in addition to, numbers. The first one, a 4×4, 15 tile puzzle, was made in 1890. The Aspiring Roboticist ( posts their sliding puzzle Valentine’s Day project using an Adafruit PyBadge programmed in CircuitPython.
