MX1919-DIP

/*
Here's an example code for controlling a DC motor using the MX1919 driver and an Arduino:

This code will rotate both DC motors clockwise at full speed for 2 seconds, stop for 1 second, rotate counterclockwise at half speed for 2 seconds, and stop for 1 second. The cycle will then repeat.

Connect the MX1919-DIP's IN1 and IN2 inputs for Motor 1 to the Arduino's digital pins 3 and 2, respectively, and connect the IN3 and IN4 inputs for Motor 2 to the Arduino's digital pins 5 and 4, respectively. Make sure to provide an appropriate power supply to the driver's motor voltage and ground pins, and connect the motors to the driver's output terminals (Motor 1 to OUT1 and OUT2, Motor 2 to OUT3 and OUT4).
