RGB LED

An RGB LED (Red, Green, Blue Light Emitting Diode) is a type of LED that combines three LEDs in one package. Each LED can emit one of the primary colors of light: red, green, or blue. By varying the intensity of each LED, a wide range of colors can be produced. RGB LEDs are commonly used in decorative lighting, displays, and various electronic projects.

Key Features:

• Combines red, green, and blue LEDs in a single package
• Can produce a wide range of colors by mixing the three primary colors
• Common anode or common cathode configurations available
• Suitable for PWM (Pulse Width Modulation) control
• Long life and low power consumption
• Compatible with various microcontroller platforms (e.g., Arduino, Raspberry Pi)

Technical Specifications:

• Type: RGB LED
• Package: 5mm or 10mm (varies by product)
• Configuration: Common Anode or Common Cathode
• Forward Voltage:
  • Red: 2.0V – 2.2V
  • Green: 3.0V – 3.2V
  • Blue: 3.0V – 3.2V
• Forward Current: 20mA per color
• Luminous Intensity:
  • Red: Typically 800 mcd
  • Green: Typically 1500 mcd
  • Blue: Typically 500 mcd
• Viewing Angle: 30-60 degrees
• Wavelength:
  • Red: 620-630 nm
  • Green: 515-530 nm
  • Blue: 460-475 nm

Applications:

• Decorative lighting
• Displays and indicators
• RGB color mixing
• DIY electronics projects
• Mood lighting
• Light shows and effects

Usage:

1. Connection:
   • Identify the anode (longest lead) and the three cathodes (shorter leads) if using a common anode RGB LED, or the cathode (longest lead) and the three anodes if using a common cathode RGB LED.
   • Connect the common lead (anode or cathode) to the appropriate voltage supply or ground.
   • Connect the red, green, and blue leads to the respective control signals or PWM outputs of a microcontroller.
2. Control:
   • Use digital output pins or PWM signals to control the intensity of each color.
   • Adjust the duty cycle of the PWM signals to mix the colors and produce various hues.
3. Programming:
   • Write code to control the RGB LED, adjusting the brightness of each color channel to achieve the desired color output.

Caution:

• Ensure proper current limiting resistors are used to prevent excessive current through the LEDs.
• Verify the forward voltage and current ratings to avoid damaging the LEDs.
• Handle the LED carefully to avoid bending the leads or damaging the package.
