ESP8266 Webserver Multiple Servo Motor Control

Welcome back, everyone! Due to popular demand, I’ve created a new project that showcases how to control multiple servo motors using an ESP8266 via a Wi-Fi Soft Access Point (AP) web server. This project is ideal for anyone looking to expand their knowledge in electronics, specifically with the use of ESP8266 and servo motors.

In this project, I will guide you through setting up a web server on the ESP8266 that allows you to control several servo motors simultaneously. By creating a web interface, you can adjust the angles of the servos using sliders and buttons from any device connected to the ESP8266’s network. This makes it a versatile project for applications in robotics, home automation, and other DIY electronics projects.

The ESP8266 is a powerful and affordable microcontroller with built-in Wi-Fi capabilities, making it perfect for IoT projects. By utilizing its Wi-Fi feature, we can create a web server that can be accessed through any web browser, eliminating the need for additional hardware or complicated setups. This makes the project more accessible and easier to implement for hobbyists and enthusiasts alike.

You can also adjust the code in the Arduino IDE according to your specific requirements. The flexibility of this project allows for various customizations, whether you need to control more servos, integrate additional sensors, or modify the web interface to better suit your needs. The Arduino IDE provides a user-friendly environment to write, compile, and upload code to the ESP8266, ensuring that even beginners can follow along and succeed.

Simply follow the steps outlined in my video, and you'll have your multi-servo controller up and running in no time. The video provides a detailed, step-by-step tutorial, covering everything from the initial setup to the final testing of your servo motors. Whether you're a seasoned maker or just starting out, this project is a great way to enhance your skills and explore the capabilities of the ESP8266.

If you face any problem regarding with Power fluctuation which with 5V. You can simply add 220uF 25V Capacitor or upgrade the voltage with 6V-7V with precaution of Microcontroller which can be burn. 

You can download the code from here in this link ElecoTechoz.

Here you can find Two code which is not connected with each other you have to connect, First one is simple paste the code and second you have to New tab by pressing (Crtl+Shift+N) and rename it this webpage.h and save and

then paste this Web code.

After Pasting all the code Select the ESP8266 board as your specifications and choose the right Com port then Compile and Upload the code on ESP8266 NodeMCU and Power it up. 

 In this project, I added a 16 bit NeoPixel Ring LED to visually indicate the servo motor movements. The Neopixel ring is connected to the ESP8266, typically using a single data pin. For this project, we use pin D5 on the ESP8266 to control the Neopixel LEDs. The Adafruit Neopixel library is essential for managing the LED animations which is In the loop, you can synchronize the Neopixel LEDs with the servo motor positions. For instance, when you update the servo angles, you can call the startLoadingEffect() to visually represent the change:

 void updateServoAndLED(int servoAngle) {

  servo.write(servoAngle);

   startLoadingEffect();

 }

This integration not only makes the project functional but also adds a dynamic visual element, enhancing the user experience by providing immediate feedback through the LED ring. The Neopixel LEDs change color and brightness in sync with the servo motor movements, making it easier to monitor the servo positions visually.

This project not only enhances your skills in working with microcontrollers and IoT but also opens up numerous possibilities for your own creative applications in robotics and home automation.
