Time	Narration
00:01	Welcome to the Spoken Tutorial on Arduino components and IDE.
00:07	In this tutorial, we will learn about: how to set up a physical connection between Arduino and a computer,
00:16	Arduino hardware and Arduino programming language.
00:21	Here, I am using: Arduino UNO Board, Ubuntu Linux 14.04 operating system and Arduino IDE.
00:31	To follow this tutorial, you should have: basic knowledge of Electronics, Arduino UNO Board, USB power cable and a computer.
00:43	First, we have to connect the Arduino board to the computer using the USB cable as shown here.
00:51	The green power LED turns ON . This indicates that the connection is working.
00:59	Now, let us see the various components that are available in the Arduino hardware.
01:06	The most important component is ATMEGA 328 microcontroller chip.
01:13	This is the heart of Arduino where you can program it to do different things.
01:20	This microcontroller contains internal ROM, RAM and also an Arduino BootLoader.
01:29	What is an Arduino BootLoader ? It is the first program which executes when the device is connected to a power supply .
01:40	These are digital pins . Each of these can be programmed as either an input or output .
01:49	Digital means they can be ON or OFF , high or low.
01:55	For example, to dim an LED , to generate audio signals etc.
02:02	The pin number 0 and 1 can be used for serial communication with other devices.
02:10	Here, 0-RX stands for receiving, 1-TX stands for transmitting.
02:20	These are Analog pins which are marked from A0 to A5 . These are only used for inputs.
02:31	They take analog signals and convert them into digital signals that the computer can understand .
02:40	These are transmit and receive LED s that are embedded on the board. These will blink when we are sending or receiving data.
02:51	This is very helpful for troubleshooting .
02:55	When you press this reset button, the program stops and restarts.
03:03	It will not erase anything off the board .
03:08	This is input voltage to the Arduino board when it is using an external power source.
03:16	These are Ground pins which give access to the lowest voltage on the board.
03:23	USB interface can be used for programming the board. And, also can be used for serial communication between the board and the computer.
03:35	We have this external power adapter to power up the board.
03:41	Next, we will see about Arduino programming language.
03:46	Arduino programs can be divided into three main parts. Control Structure statements , Operators, variables and constants,
03:57	and, Functions.
04:00	The control statements are: if, if..else, for, while, do..while, switch case etc .
04:11	These are the same as in any programming language.
04:16	Then, we have arithmetic operators, comparison operators and boolean operators.
04:24	We have variables and constants as in other programming languages.
04:31	These are built-in functions such as pinMode(), digitalWrite(), digitalRead(), delay(), analogRead(), analogWrite() etc.
04:46	These are the important functions which are mostly used in the Arduino projects.
04:52	I'll show you how to refer this programming language of Arduino IDE .
04:58	Let us open the Arduino IDE .
05:01	Click on the Help menu in the Arduino IDE . Then click on Reference.
05:08	This opens an offline page in your browser.
05:12	For example, if you want to refer the 'digitalWrite()' built-in function, just click on the function name.
05:22	Here you can see the description, syntax and a sample program of digitalWrite() function.
05:31	There are many built-in functions and we can refer to this manual depending upon our requirement.
05:39	We will be learning about some of the important built-in functions in the subsequent tutorials.
05:47	This brings us to the end of this tutorial. Let us summarize.
05:52	In this tutorial, we learnt about: how to set up a physical connection between the Arduino and computer,
06:00	' Arduino' hardware, Arduino programming language.
06:05	As an assignment- open the Arduino IDE.
06:09	Click on the Help Menu and select Reference.
06:14	Go through the built-in functions such as delay(), pinMode() and digitalRead() etc.
06:22	The video at the following link summarizes the Spoken Tutorial project. Please download and watch it.
06:30	The Spoken Tutorial Project team: conducts workshops and gives certificates to those who pass an online test. For more details, please write to us.
06:42	Do you have questions in THIS Spoken Tutorial? Please visit this site.
06:47	Choose the minute and second where you have the question. Explain your question briefly. Someone from our team will answer them.
06:57	Spoken Tutorial project is funded by NMEICT, MHRD, Government of India. More information on this mission is available at this link.
07:07	This tutorial has been contributed by FOSSEE and Spoken Tutorial Project, IIT Bombay. Thanks for watching.
