| 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  '''variable'''s  and  '''constant'''s  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.'''
