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.
