Video 8: Controlling RGB Full Color LED through Pulse Width Modulation (PWM)

This tutorial dives into the essentials of using RGB LEDs and Pulse Width Modulation (PWM) in Arduino programming, demonstrated through various LED control projects.

• RGB LEDs: Introduction to RGB LEDs and how they can be used to produce a wide range of colors by mixing red, green, and blue primary colors.

• Pulse Width Modulation (PWM): Explanation of PWM and how it is used to simulate analog output by controlling the duty cycle of digital signals.

• AnalogWrite Function: Demonstrates using the analogWrite function to control the brightness of LEDs and mix colors through PWM.

• LED Glowing and Fading Effects: Guides on creating glowing and fading effects on RGB LEDs by gradually changing the duty cycle.

• Color Mixing: Shows how to mix different intensities of red, green, and blue to produce various colors and create a smooth color transition.

• Automatic RGB LED Project: Encourages building a project where the RGB LED changes colors automatically, using concepts from the tutorial.

• Challenge Activity: Improve the program to create an automatic color-changing RGB LED project with smooth transitions between colors.
