Story

In this project, we used an L293D Motor Driver Shield to control the direction and angle of a servo motor. This project is perfect for beginners interested in robotics and automation. Whether you're planning to create a future robotics endeavor or just exploring, this project is a great starting point.

Wiring Diagram

1. Motor Driver Shield Servo Motor

Connect the signal wire, the power wire, and the ground wire of the servo motor to the SER1 or SERVO_2 pins on the motor driver shield. The servo motor has 3 wires, which makes it compatible with these pins.

2. Power Supply

Connect the battery pack to the power input terminals on the motor driver shield.

3. Arduino Uno

Plug the L293D motor driver shield directly onto the Arduino Uno.

Explanation

Servo Control: The Servo library is used to control the servo motor.
Angle Control: The myServo.write(angle) function sets the servo motor to a specific angle (0 to 180 degrees).
Timing: The delay() function is used to hold the servo position for a specific amount of time.

Demonstration

Code

Code

#include <Servo.h>

Servo myServo; // Create a Servo object

void setup() {
  myServo.attach(9); // Attach the servo to pin SER1 on the shield)
}

void loop() {
  // Move the servo to 0 degrees
  myServo.write(0);
  delay(2000); // Hold for 2 seconds

  // Move the servo to 180 degrees
  myServo.write(180);
  delay(2000); // Hold for 2 seconds

  // Move the servo to 90 degrees
  myServo.write(90);
  delay(2000); // Hold for 2 seconds

  // Move the servo back to 0 degrees
  myServo.write(0);
  delay(2000); // Hold for 2 seconds
}
