Avoiding

The document contains Arduino code for controlling a robot's movement using servo motors and ultrasonic sensors. It defines functions for moving forward, backward, turning, and stopping based on distance measurements. The code utilizes the NewPing library to read distances and make decisions on movement direction to avoid obstacles.
