Desktop Tetris Building
Play a game of Tetris on a custom 3D printed LED matrix inspired by the MIT Green Building hack. The project is powered by an Adafruit Feather RP2040 PropMaker running CircuitPython and a Mini Gamepad STEMMA QT.
It also features a 1200mAh lipo battery for portable gameplay.
The 9x13 grid is made using a strand of 117 NeoPixel LED pebbles which are fitted into a 3D printed grid and diffused with a piece of black LED acrylic.

The gamepad STEMMA QT features standard buttons and a joystick. Use the joystick to move the shapes (Tetrominoes) on the grid, A button to rotate and B button to drop to the bottom of the grid. The start button begins the game and pauses during gameplay.
