Scroll HAT Mini’s 119 LEDs are plenty for scrolling text, and the individual PWM brightness control over each pixel opens up a whole heap of potential for swish animations. The buttons could be used to toggle through modes or menus, for playback control, or even to control simple games. The pre-soldered header means there’s no pesky soldering!
Use Scroll HAT Mini as a scrolling message display for your tweets, the weather or the news. There’s even enough pixels for simple games like Tetris, Pong, or snake, using the buttons for controls.
