5mm RGB LED – 4-Pin Multicolor Through-Hole LED
The RGB LED is a multicolor light-emitting diode that combines three individual LEDs—Red, Green, and Blue—inside a single transparent package.
By adjusting the brightness of each color independently, the RGB LED can produce a wide range of colors and lighting effects.
Featuring a 4-pin through-hole design, this LED is ideal for Arduino, ESP32, Raspberry Pi electronics, DIY projects, decorative lighting, and electronic indicators.

Connection with Arduino or ESP32
- Identify the RGB LED's common terminal and polarity.
- Connect the common terminal according to the LED type.
- Connect the Red, Green, and Blue pins to suitable GPIO outputs through individual current-limiting resistors.
- Use PWM signals to adjust the brightness of each color.
- Combine different brightness levels to generate custom colors and lighting effects.
Applications
- Arduino and ESP32 Projects
- Raspberry Pi Electronic Circuits
- RGB Lighting Effects
- LED Status Indicators
- DIY Electronics
- Educational STEM Projects
- Decorative Lighting
- Breadboard Prototyping
- Electronic Displays and Indicators
Important Notes
- Always use a suitable current-limiting resistor for each LED color channel.
- Do not connect the LED directly to a power supply without current limiting.
- Common anode and common cathode versions require different wiring and control logic.
- Forward voltage and current ratings vary between the Red, Green, and Blue LED elements.
- This is a standard RGB LED, not an individually addressable LED such as WS2812B.
