steppermotor

Connect the stepper motor to an audio amplified board like in the image, and connect the audio and power input. Add an optional resitance between the audio board and the stepper motor to prevent too large currents through your motor. Run the script 'steppermotor.m' to control the motor. Use velocities between 1 and 30, negative number of steps results in a movement in the other direction. If the motor does not move, check the volume settings of your computer.
