A single digit split-flap display demo using a microcontroller to control the 28BY-48 stepper motor. A hall effect sensor to detect the 0 position and pegs which can be melted to hold the sensor in place. A 607 bearing is used to ensure smooth rotation.
The middle gear is a little janky, working on a fix to make it more stable.
