Control a motor with pi pico

this is how you can controll a stepper motor by defining the digital pins on the Arduino board to control direction and steps, then set up the direction and steps pins as outputs, we start at off state for stability.
Then we give the direction pin power to turn the motor at one direction by iterating the stepps to 200. next we turn off the direction to rotate in the other direction
