Lesson 11: RGB LED Flasher in Two Colors

11.1 Overview

In this lesson we are going to make a flasher using RGB LED.

11.2 Components Required

1 x Breadboard Power Supply
1 x 9V Battery
1 x 9V Battery Connector
1 x Breadboard 830p
1 x RGB LED Common Cathode
2 x 220 Ω resistor
2 x 100 KΩ resistor
2 x 2N2222 NPN Transistor
2 x 10 uF Capacitor
5 x M-M wires (Male to Male jumper wires)

11.3 Component Introduction

RGB LED
It is the same as the normal LED, but there are three LEDs inside of it (Red, Green and Blue).

All of the LEDs are sharing the Cathode or the Anode, so there are four terminals for the three
LEDs, below you can see the schematic symbols for both of them.
