![]() ![]() Pulse Width Modulation (PWM) is a technique used to control the amount of power delivered to a device, such as an LED or motor. Additionally, some familiarity with PWM signals is necessary to change the LED brightness. Overall, building this project requires a working understanding of programming in Arduino IDE, as well as some web development knowledge. Utilize Pulse Width Modulation (PWM) to change the brightness of the LED based on the slider value.In the ESP8266 code, read the value of the slider and store it in a variable.Use AJAX and JavaScript to transmit the slider value to the ESP8266 and update the web page without reloading it.This will require knowledge of HTML, CSS, and JavaScript. Create a program in the Arduino Integrated Development Environment (IDE) that establishes a web server and displays a slider on the web page.Begin by setting up the hardware components, which involves connecting an LED to the ESP8266 NodeMCU board.To build a web server using ESP8266 NodeMCU board and a slider to control LED brightness, you can follow these steps: ![]() Not only is this project fun and rewarding, but it also provides a great opportunity to learn more about the intersection of electronics and web development. With some basic electronics knowledge and coding skills, you should be able to complete this project and create a fully functional web server that can be controlled by a slider to adjust the LED brightness. From there, the program will use Pulse Width Modulation (PWM) to change the brightness of the LED based on the value of the slider. Once the ESP8266 receives the slider value, it will read the value and store it in a variable. ![]()
