In this Visuino project, you will learn how to use the ESP32-C3 LCD kit to control an RGB LED’s brightness with a rotary encoder. Turning the encoder adjusts the brightness in steps from 0 to 1 with 0.1 increments, and the current brightness level is shown directly on the LCD display. Pressing the encoder’s button instantly sets a random LED color, making the project both fun and interactive. This tutorial is perfect for learning how to: Configure and Use the rotary encoder on ESP32-C3 Display live brightness values on the LCD screen Randomize LED colors with a simple button press Use Visuino Visual Programming to quickly design interactive IoT projects Bring your ESP32-C3 LCD kit to life with this engaging RGB LED brightness controller!
