This C++ code is used to control a servo motor...

This C++ code is used to control a servo motor using the Servo library. Here's what it does:

1. Include the Servo library:
   #include <Servo.h>
   This imports the Servo library, which is used to control servo motors.

2. Create a Servo object:
   Servo servo_5;
   This declares a servo object named servo_5. This object will be used to interface with and control the servo motor.

3. Setup function:
   Inside the setup() function:

   servo_5.attach(5, 500, 2500);
   

   This attaches the servo motor to pin 5 on the Arduino, and specifies the range of the pulse width:

   • 500 µs (microseconds) represents the minimum pulse width.
   • 2500 µs represents the maximum pulse width. These values configure the servo motor's full sweep (0 to 180 degrees).

4. Loop function:
   Inside the loop() function:

   servo_5.write(180);
   delay(3);
   servo_5.write(0);
   delay(3);
   

   • servo_5.write(180); moves the servo motor to 180 degrees (extreme position).
   • delay(3); pauses the program for 3 milliseconds.
   • servo_5.write(0); moves the servo motor to 0 degrees (opposite extreme position).
   • delay(3); pauses the program for another 3 milliseconds.

   This creates a rapid alternating movement of the servo between 0 and 180 degrees with a 3 ms delay between movements. Essentially, the servo will try to "oscillate" back and forth, but the timing (3 ms delay) is extremely short and may not allow the servo to reach its target positions due to physical limitations of the motor.
