|-
| 00:01
| Welcome to the''' Spoken Tutorial''' on''' AVR-GCC programming through Arduino.'''

|-
| 00:08
| In this tutorial, we will learn to: Interface a''' seven segment display''' to''' Arduino board'''.

|-
| 00:15
| Write an''' AVR-GCC''' program to display a digit on '''seven segment display '''and Display digits 0 to 9 on the '''seven segment display.'''

|-
| 00:27
| To follow this tutorial, you should have basic knowledge of :

|-
| 00:31
| '''Electronics '''

|-
| 00:34
| '''C Programming '''and '''AVR-GCC'''

|-
| 00:39
| To record this tutorial, I am using: '''Arduino UNO Board '''and '''Ubuntu Linux '''operating system version 14.04

|-
| 00:50
| '''GCC '''stands for''' GNU Compiler Collection.'''

|-
| 00:54
| It is a '''compiler''' which supports various programming languages.

|-
| 00:59
| '''AVR-GCC '''is a part of '''GCC''' and supports compiling '''C programs''' for '''AVR microcontrollers.'''

|-
| 01:08
| Since '''Arduino''' uses '''ATMEGA328P''', this is a suitable '''compiler'''.

|-
| 01:15
| We also require some external devices such as: '''Seven-Segment Display'''

|-
| 01:22
| '''220 ohm Resistor'''

|-
| 01:26
| '''Breadboard'''

|-
| 01:28
| '''Arduino UNO Board'''

And '''Jumper Wires'''

|-
| 01:33
| In this experiment we will be using the '''common anode seven-segment display.'''

|-
| 01:39
|Please refer to the basic level tutorials of this series to know more about '''Seven segment display'''.

|-
| 01:46
| Refer the '''pin mapping''' for '''Arduino''' and '''microcontroller'''.

|-
| 01:51
| Do the circuit connection as shown here.

|-
| 01:55
|The '''Dot''' pin of the '''Seven Segment Display''' is connected to the '''pin 13''' of the '''Arduino'''.

|-
| 02:02
|Any one of the '''common''' pins is connected to the '''+5Volts''' through a '''resistor'''.

|-
| 02:09
| This is the live setup of the connection.

|-
| 02:12
| Now we will write an '''AVR-GCC program''' to blink the '''Dot LED''' on the '''seven segment display'''.

|-
| 02:22
| We need to install '''AVR-GCC assembler''' and a '''AVR-LIBC library'''.

|-
| 02:29
| '''AVR-GCC''' will generate a '''hex''' file and upload it to '''Arduino board'''.

|-
| 02:35
| '''AVR-LIBC '''contains the required '''library files''' that can be used in the program.

|-
| 02:42
| Open the '''terminal''' by pressing '''Ctrl + Alt + T''' keys together.

|-
| 02:48
| Type, '''sudo space apt hyphen get space install space avr hyphen libc space gcc hyphen avr '''

And press '''Enter'''.

|-
| 03:03
| Enter the '''administrative '''password if prompted and press '''Enter.'''

|-
| 03:09
| We can see the installation process has begun.

|-
| 03:13
|Press ''''Y'''' wherever there is a prompt during installation to confirm the configuration.

|-
| 03:20
|Installation will take some time to complete depending upon the internet speed.

|-
| 03:26
| We can see that the installation has been completed successfully.

Let me clear the '''terminal'''.

|-
| 03:34
| Now let us connect the''' Arduino board''' to the computer.

|-
| 03:38
| To check the '''port number '''of '''Arduino''', I'll type '''ls space forwardslash dev forwardslash ttyACM asterisk''' and press '''Enter'''.

|-
| 03:51
| We can see the output as shown. Here''' ttyACM0''' represents the '''port number '''of '''Arduino'''.

|-
| 04:00
|You may get a different '''port number'''. Make a note of your '''port number'''.

|-
| 04:06
| Download the file '''Makefile '''from the '''Code files''' link of this tutorial.

|-
| 04:12
| '''Makefile''' enables us to create a ''' dot hex''' file and upload it to '''Arduino'''.

|-
| 04:19
| Save the '''Makefile''' in the folder where you will be saving the '''C''' program.

|-
| 04:24
| Let us write the''' avr-gcc''' program to blink the '''Dot''' '''LED''' and upload it to the '''microcontroller'''.

|-
| 04:32
| Open any text editor and type the following.

|-
| 04:36
| We have to include the '''libraries''' required for our program.

|-
| 04:41
| '''avr slash io dot h''' contains all the basic '''libraries''' required to perform the input and output operations.

|-
| 04:50
| '''util slash delay dot h''' contains the '''libraries''' for the '''delay function.'''

|-
| 04:56
| '''Arduino board''' has an LED at PB5.

|-
| 05:00
| Set '''PB5''', that is '''pin 13 '''of '''Arduino '''as output.

|-
| 05:05
| Sending 0 to '''PB5''' turns '''on''' the '''LED.'''

|-
| 05:09
| Sending 1 to '''PB5''' turns '''off''' the '''LED'''.

|-
| 05:13
| These two steps will run in an infinite '''while loop''' making the '''LED''' blink.

|-
| 05:19
| Source code that are used in this tutorial are available in the '''Code Files''' link of this tutorial.

You can download and use it.

|-
| 05:28
| I’ll save the code as '''dot hyphen blink dot c''' in the '''Downloads''' folder.

|-
| 05:37
| Switch to the '''terminal'''.

|-
| 05:39
| Go to the '''Downloads''' folder where '''dot hyphen blink dot c '''file is saved.

|-
| 05:45
| Type, '''make space FNAME in capital equals dot hyphen blink ''' and press '''Enter'''.

This '''command''' creates a ''' dot hex''' file and uploads it to the '''Arduino'''.

|-
| 06:00
| Now, you can see that''' '''the '''Dot''' '''LED''' in the '''seven segment''' is blinking.

|-
| 06:06
| Next, we will display '''digit 2''' on the '''seven segment display.'''

|-
|06:11
| To display '2', '''a''','''b,d,e,g segments '''should be high and the other '''LEDS''' should be low.

|-
| 06:19
| '''Pins a, b, c, d, e, f '''and''' g '''of the '''seven segment display''' are connected to the '''pins 2, 3, 4, 5, 6, 7''' and '''8''' of the '''Arduino''' respectively.

|-
| 06:32
| The common '''pin''' is connected to '''+5Volts''' through '''resistor'''.

|-
| 06:37
| Let us see the live connection setup.

|-
| 06:42
| Let us see the source code for this program.

|-
| 06:46
| Open any text editor and type the following code.

|-
| 06:50
| The first two lines of the code in the '''main function''' set '''pins 2 '''to '''8 '''as '''output pins.'''

|-
|06:58
| The codes inside the '''while loop '''are used to control the state of the respective '''LEDs'''.

|-
| 07:05
| Sending 0 will cause the '''LED''' to glow and sending 1 will turn it off.

|-
| 07:11
| Save it as '''two.c '''file.

|-
| 07:15
| Switch back to the '''terminal'''.

Clear the '''terminal''' now.

|-
| 07:21
| Type '''make space FNAME''' in capital '''equals two''' and press '''Enter'''.

|-
| 07:30
| Now you can see that the digit two in the '''seven segment''' is glowing.

|-
| 07:38
| Pause the tutorial and do the below assignment. Modify the above code to display any other '''digit''' from '''0 '''to''' 9'''.

|-
| 07:48
| Next, we will display the numbers 0 to 9 on the '''Seven Segment Display'''.

|-
| 07:54
| Setup remains the same.

|-
| 07:57
| Let us see the source code for this program. Open any text editor and type the following code.

|-
| 08:04
| The '''for loop''' is used to count from 0 to 9.

Each time, the variable ‘''' i ‘ '''is incremented by one and the value is passed to '''sevenseg function'''.

|-
| 08:16
| The '''sevenseg function '''receives an integer ranging from 0 to 9.

Based on the input, the '''case''' structure is executed.

|-
| 08:27
| Thus displaying the '''digits '''from '''0 '''to '''9'''.

|-
| 08:32
| Save it as '''counter.c '''file.

|-
| 08:36
| Switch back to the '''terminal''' and clear it.

|-
| 08:40
| Type '''make space FNAME''' in capital '''equals counter''' and press '''Enter'''.

|-
| 08:50
| Now we can see the '''digits 0 '''to '''9 '''is displayed in the '''seven segment display'''.

|-
| 09:02
| This brings us to the end of this tutorial. Let us summarize.

|-
| 09:06
| In this tutorial, we learnt to Interface a''' Seven-segment display''' to''' Arduino board '''

|-
| 09:13
| Write an''' AVR-GCC''' program to display a digit on '''seven-segment display '''and

|-
| 09:19
| Display '''digits 0 '''to '''9 '''on the '''Seven segment display.'''
