LESSON 6: RGB LED

Introduction
Before in our previous lessons we used different types of LEDs (in our kit, we have 5mm LEDs in different colours)
the RGB LED is a little bit different.
The RGB stands for Red, Green and Blue. It allows us to control 3 colours and using those colours, generate lots of
colours!
We will learn how to activate each of the colours separately and later on being able to combine them together and
create different range of colours.
The RGB LED is very useful for any applications, if you need LED for example for indications purposes, there is no
need to use red LED for one scenario and blue for another one. We can use RGB LED and change the colours based
on our needs!
