Projects using this component
RGB Led Usage
Basic usage project that sequentially turns on and off the red, green and blue colors of the RGB LED. Teaches common cathode RGB LED control.
Smooth Color Transition with RGB Led
A project that creates a soft rainbow effect by gradually transitioning the colors of an RGB LED with analogWrite. Teaches the logic of color mixing and transition animation with PWM.
RGB Led Control with Keypad
This project allows you to manage the RGB LED between modes and colors via the 4x4 Keypad. Thanks to the millis() structure, commands are processed without delay. 🎮 User Guide: Key A: Fixed speed Fade effect. B Key: Smooth transition with adjustable speed. C / D: Increases / Decreases the effect speed. 1 - 9: Quick Master Color selection. * / #: Special Intermediate Colors (Pink, Light Green, etc.). 0 Key: Turns off the system.
ESP32 RGB LED Control
Unlimited color generation with a single RGB LED instead of 3 separate LEDs. As in Arduino, we make a rainbow transition by setting the R/G/B values with analogWrite(). Color theory (such as red+green=yellow) is seen practically.
ESP32 Color Mixer Light (3 Potentiometers + RGB LED + OLED)
A smart color-mixing lamp that lets you mix any color you want by turning three potentiometers with the ESP32! As you turn the red, green, and blue potentiometers, the common-cathode RGB LED changes color in real time. The SSD1306 OLED display shows real-time values for each color in the 0–255 range, visual fill bars, and the HEX web color code (such as #FF8040). A mini professional color studio—teaches RGB color theory, ADC analog reading, brightness control via PWM, and I2C display design all
Raspberry Pi Pico RGB LED Color Cycle (3-Channel PWM, GP11-13)
One LED, millions of colors! 🌈 An RGB LED actually contains 3 LEDs: **red, green and blue**. Driving each with its own Pico **PWM** channel mixes the colors: red + green = yellow, green + blue = cyan, all three = white. Here the LED cycles through 8 colors. Learn **multiple PWM channels**, **defining functions** (`def renk(...)`), **RGB color mixing** (how screens and smart bulbs work), **8-bit → 16-bit conversion** (`x257` maps 0–255 to 0–65535), **common cathode vs common anode** LEDs and **st
