Program is divided in tow parts Web Page ( index.h) and Main Hardware Code ESPservo.ino ESPservo.inoīefore uploading code make changes in SSID and Password as per your wifi /* The Arduino IDE Code for the Web Controlled Servo using ESP8266 tutorial is given below. Its other pins are power supply pins and are connected to 5V and GND (Red and Brown). Pin D5 of NodeMCU will provide the necessary PWM signal to the Servo (Orange). connecting ESP8266 to WiFi, getting information from Web and finally controlling the Servo. The main program responsible for everything i.e.

The circuit diagram for Web Controlled Servo using ESP8266 WiFi Module is given in the image below. the ESP8266, which acts as the Server, and the Laptop (or a Mobile Phone), which is the client, must be connected to the same WiFi network. One important thing to remember here is that both the Server and client should be on the same network i.e. The NodeMCU, upon receiving the value, transmits corresponding PWM to servo, which then changes the position of the Servo Motor according to the value. The slider in the web page sends the angle values and is received by the NodeMCU, which acts as a Web Server. In case of a Web Controlled Servo Motor using ESP8266, ESP8266 drives the Servo Motor but the input isn’t from a POT but a Web Page we created with AJAX. Depending on the position of the POT, the PWM value of the Servo Motor input changes and consequently the position of the Servo Motor’s shaft changes. Normally, in order to control a Servo Motor with Arduino (for example), all you need is a Servo Motor, Arduino and a Potentiometer. When this web page is accessed from a laptop or mobile phone that is connected to the same WiFi Network as the ESP8266, you can control the position of the Servo Motor by adjusting the knob. I’ll be creating a simple Web Page (HTML) with a circular knob. Arduino has library for Servo Motors and it handles all the PWM related things to rotate the servo, you just need to enter the angle to which you want to rotate and there is function servo1.write (angle) which will rotate the servo to desired angle. Servo Motors are one of the most commonly used motors in both industries and DIY Projects. The complete Arduino code for Multiple Servo Control is given at the end.

In this tutorial ESP8266 we will see How to control Servo motor using NodeMCU web server? where the position of the Servo Motor can be controlled through a Web Page (within the same WiFi Network).
