A stepper motor from an old scanner is manually driven by L298N dual H-bridge connected to Arduino UNO.

This project is an intermediate step towards our own DIY slider. It consists of the microcontroller (Arduino UNO), the input (two trigger for forward and backward movement of the stepper motor), the motor driver (L298N) and the stepper motor of an old scanner (Mitsumi M35SP-11NK). Press the buttons and the motor moves the scanner slider.
