Description

The description “2pcs RGB LED Common Cathode” refers to a set of two RGB (Red, Green, Blue) LEDs, and the term “Common Cathode” specifies the electrical configuration of these LEDs. Here’s a breakdown of what this description typically means:

Quantity:

The set includes a total of two RGB LEDs. This is the number of LED units you will receive when you purchase this particular pack.
RGB LED:

Each LED in the set is capable of emitting light in three primary colors: Red, Green, and Blue. These colors can be combined to produce a wide range of colors, allowing for color mixing.
Common Cathode:

The term “Common Cathode” indicates the electrical configuration of the RGB LEDs. In a common cathode configuration, the cathodes of the three individual LEDs (Red, Green, and Blue) are connected together and share a common connection, while each anode is separate. To light up a specific color, a positive voltage is applied to the respective anode, and the cathode is connected to the ground (GND) or the low side of the power supply.
Color Mixing:

By varying the intensity of each color (Red, Green, and Blue), different colors can be achieved. For example, turning on the Red and Green LEDs simultaneously creates a yellow color.
Applications:

RGB LEDs are commonly used in various applications where dynamic and colorful lighting is desired. They are used in decorative lighting, displays, signage, entertainment systems, and electronic projects.
Control:

The intensity of each color in the RGB LED can be controlled using pulse-width modulation (PWM) signals. This allows for the creation of a wide spectrum of colors.
Voltage and Current:

The voltage and current requirements for each LED, as well as the overall RGB LED, depend on the specific model. Always refer to the datasheet or specifications provided by the manufacturer for accurate electrical characteristics.
Usage:

This set of RGB LEDs is suitable for various electronic projects, DIY lighting applications, mood lighting, and any other scenario where color-changing capabilities are desired.
When using these RGB LEDs in a circuit, it’s important to follow the manufacturer’s specifications, especially regarding voltage, current, and control signals. Additionally, ensure that your microcontroller or driver circuit is capable of providing the necessary control signals for color mixing.
