ESP8266 Servo Motor Project

This project demonstrates how to control a servo motor using an ESP8266 microcontroller. Servo motors are widely used in applications requiring precise control of angular position, such as in robotics, automation, and remote control systems.

Components Needed

Circuit Diagram

Circuit Setup

1.Connecting the Servo Motor to ESP8266:

Signal Pin: Connect the signal (PWM) pin of the servo motor to GPIO pin D5 on the ESP8266.

Power Pins: Connect the VCC (usually 5V) and GND pins of the servo motor to an appropriate power source. Ensure a common ground (GND) connection between the ESP8266 and the servo motor.

Instructions

1.Setup:

Include the necessary libraries (ESP8266WiFi.h and ESP8266Servo.h) for Wi-Fi functionality and servo control.

Define the GPIO pin connected to the servo motor (D5).

Initialize serial communication at a baud rate of 9600 for debugging purposes.

Attach the servo motor to the specified GPIO pin using myServo.attach(SERVO_PIN).

Move the servo to an initial position (90 degrees) and print a message to the Serial Monitor.

2.operation:

In the loop() function:

The for loops in the loop() function increment or decrement the servo position, and the myServo.write(pos) command sets the servo to the specified position.

Applications

robotics: Control robotic arms or joints with precise angular movements.

automation: Actuate levers or mechanisms requiring controlled positioning.

Remote Control Systems: Control the orientation of components, such as antennas or camera gimbals.

Notes

Servo Power Requirements: Ensure the servo motor has an adequate power supply, as the ESP8266's onboard power may not suffice for larger servos.

Delay Tuning: Adjust the delay value to control the speed of the servo movement. Smaller delays result in faster movements.

Initial Positioning: The servo is initialized to a neutral position (90 degrees) at the start for a reference point.
