RGB Picker Web Interface – My First C++ and Arduino Project

A simple color picker for controlling the built-in RGB LED on the Arduino Nano ESP32. Welcome! After almost a year, I'm finally publishing a new post. This time, I'm diving into C++ and Arduino to create an interactive RGB Picker Web Interface to select colors and display them on the RGB LED. This project sets up an ESP32 Nano as a web server that allows users to control an RGB LED using a color picker on a web page. It enables both WiFi Station (STA) and Access Point (AP) modes, allowing users to connect either through an existing network or directly to the ESP32's own WiFi hotspot. The full code is available on GitHub . Libraries Used #include <Arduino.h> #include <ArduinoJson.h> #include <AsyncJson.h> #include <AsyncTCP.h> #include <ESPAsyncWebServer.h> #include <WiFi.h> Arduino.h : Core Arduino functions. ArduinoJson.h : JSON handling. AsyncJson.h : JSON support for the web server. AsyncTCP.h : Handles non-blocking TCP connections. ESPAsyncWebServ…
