3.4.2 RGB LED
This chapter explains how to control RGB LED connected to Arduino board using Arduino
Sketch. We explore how to access PWM (Pulse Width Modulation) Arduino.
In this scenario we build Arduino Sketch application to control RGB LED color using Ar-
duino Analog output (PWM). RGB LED has 4 pins that you can see it on Figure below.
