Part 1: Introduction
In this lesson we learn how to use LED and Push button in this 10 LED projects. Wiring diagram is shown, code is fully explained and demonstrated with multiple change of settings for each project. We read potentiometer's voltage and display voltage by turning each LED on to represent voltages. A Simple traffic light project.
This code is part of video lecture. This project 10 code. We have three LEDs, Red, Green and Yellow.
We will set the time for each LED to be turned ON. Of course the timing can be changed and in some countries
the sequence may vary like yellow and gree might be ON at the same time for short period. But this is very simple basic Traffic light.

****** 10 Projects explained in this video
* 1-LED ON OFF
* 2-LED ON/OFF with push button
* 3-LED ON/OFF toggle with push button
* 4-Fading light of LED
* 5-Fading light of LED using push button
* 6-See Saw with LED

* What pars we need:
* -Of course Arduino board (UNO , Nano, Mega or any)
* -RED, GREEN and YELLOW LED eitehr 5mm or 3mm
* -200ohm to 1000 ohrm resistor for each LED
* -Some dupont wires to connec
* -If don't want to solder, then use breadboard
