  1. /*
  2. Here's a basic example code for using an Arduino to control the Motor Driver 43A BTS7960. This code assumes that you have already connected the motor driver to the Arduino board as per the appropriate wiring. The code will make the motor run forward and backward with a 2-second delay between each movement.
  3.  
  4. Upload this code to your Arduino board and adjust the motorSpeed variable as necessary to control the motor speed. Make sure your connections and power supply are appropriate for the motor you're using.
