Introduction to Arduino and RGB LED Module

• Overview of how Arduino is utilized in everyday applications.

• Significance of understanding RGB LED modules for 9th-grade learners.

RGB LED Module: Fundamentals

Purpose and Functions

• The RGB LED Module comprises Red, Green, and Blue lights.

• It is designed to emit various colors by blending light.

• Understanding wiring connections with breadboards and LEDs is crucial.

Key Learning Objectives

• Identify and name the components of an LED.

• Execute wiring connections accurately.

• Determine the code for creating color combinations using RGB modules.

• Recognize the three primary colors of light: Red, Green, and Blue.

The RGB Color System

• The RGB color space enables the creation of colors via combinations of its three primary colors.

• An RGB LED consists of three individual colored LEDs combined in one unit.

• Typically, an RGB LED has four leads: one for each color and one for a common cathode or anode.

Color Emission and Mixing

Color Production

• The RGB LED can create various colors by modulating the brightness of Red, Green, and Blue LEDs.

• Adjusting light intensity through circuit modification results in the production of nearly all colors.

Color Combinations

• Each color corresponds to a specific blend of intensities:

  • Red: HIGH, LOW, LOW (255, 0, 0)

  • Green: LOW, HIGH, LOW (0, 255, 0)

  • Blue: LOW, LOW, HIGH (0, 0, 255)

  • Yellow: HIGH, HIGH, LOW (255, 255, 0)

  • Cyan: LOW, HIGH, HIGH (0, 255, 255)

  • Magenta: HIGH, LOW, HIGH (255, 0, 255)

  • White: HIGH, HIGH, HIGH (255, 255, 255)

Start-Up Code for RGB LED

Basic Code Structure

• Begin by assigning LED pin numbers: int LEDred = 6; int LEDgreen = 7; int LEDblue = 8;

• Configure the LED pins as outputs.

• Utilize a void loop to alternate colors with delays: Example: digitalWrite(LEDred, HIGH); delay(1000);

Color Control Function

• Implement the setColor(int red, int green, int blue) function for enhanced control.

• This function uses analogWrite() to adjust brightness levels of each LED: analogWrite(LEDred, red); analogWrite(LEDgreen, green); analogWrite(LEDblue, blue);
