An RGB LED module with a common-cathode full-colour LED and built-in current-limiting resistors for each channel. Control the red, green, and blue channels independently via PWM to mix any colour. Compatible with Arduino and other 5 V microcontrollers.
Key Features
- Full-Colour RGB LED – Common-cathode, through-hole LED
- Built-In Resistors – Current-limiting resistors on R, G, and B channels prevent burnout
- PWM Colour Mixing – Adjust each channel to create any colour
- 5 V Compatible – Works with Arduino and standard microcontrollers
Specifications
- Operating Voltage: 5 V
- LED Type: Common-cathode RGB
- Interface: 4-pin (R, G, B, GND)
Ideal For
- Arduino colour-mixing projects
- Status indicators and mood lighting
- Learning PWM control
Package Contents
- 1× RGB LED module
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
