A strange video game controller meant to play Online Tetris.
Story
What happens when you mix cardboard and wires together? You get the Tetromino controller. This strange video game controller is made for Online Tetris. It is a box with 5 buttons, all of them are in 3 different colors based on what they do. The yellow buttons control moving left and right, the green buttons control block rotations, and the black button on top controls the drop move to drop the blocks faster.
These five buttons are wired to a Circuit Playground Express chip and the code allows the button presses to be mapped out specifically for the keyboard controls of Tetris. They are mapped out to the arrow keys and the Z key just like the online Tetris game’s controls. The Circuit Playground Express is powered by a USB connecting to a computer to play the game. If you want a little bit of challenge when playing Tetris online, this controller is for you.
