|-
|| 00:08
|| In this tutorial, we will learn about
|-
|| 00:12
|| '''Arduino - Scilab toolbox'''

|-
|| 00:15
|| Interfacing '''Arduino''' with '''Scilab'''

|-
|| 00:19
|| Interfacing''' Arduino '''with '''Xcos'''

|-
|| 00:23
|| To record this tutorial, I’m using
|-
|| 00:28
|| '''Ubuntu Linux '''OS version 18.04 

|-
|| 00:32
|| '''Arduino Shield''' and

|-
|| 00:34
|| '''Arduino Uno Board'''

|-
|| 00:37
||To follow this tutorial, you should go through the below '''Arduino spoken tutorial.'''

|-
|| 00:44
||  '''Getting ready for Arduino FLOSS.'''

|-
|| 00:48
|| In the above tutorial, you will learn
|-
|| 00:52
|| How to download the '''e-book''' and code files required for the experiments.
|-
|| 00:59
|| How to upload and '''compile Arduino programs''' in '''Arduino IDE.'''
|-
|| 01:05
|| About '''FLOSS Firmware'''
|-
|| 01:08
|| If you are not familiar with '''Scilab''', go through the''' Scilab spoken tutorials''' on this website.
|-
|| 01:16
|| You will learn about:
Introduction to '''Scilab'''
|-
|| 01:21
|| Introduction to '''Xcos'''
|-
|| 01:24
|| '''Scilab''' and '''Xcos''' interface and
'''Simulation''' 
|-
|| 01:30
|| I have downloaded '''Microcontroller Programming with Arduino, Scilab and Xcos ebook'''.
|-
|| 01:38
|| Refer to chapter 3 in the book.
|-
|| 01:42
|| Follow the steps given for the '''installation''' of '''Arduino IDE '''and''' Scilab'''
|-
|| 01:49
|| '''Installation''' steps are given for '''Windows''' and '''Linux OS.'''
|-
|| 01:55
|| '''Xcos''' comes pre-installed with '''Scilab'''. Hence a separate installation of '''Xcos''' is not required.
|-
|| 02:05
||  The experiments that are covered in the book are tested in '''Ubuntu Linux 18.04 '''and '''Windows 10 OS.'''
|-
|| 02:15
|| Connect the '''Arduino uno board''' with '''Arduino shield''' to the '''USB port''' of the computer
|-
|| 02:23
|| Note the below points:
1. Launch '''Arduino IDE'''
|-
|| 02:29
|| 2. Check the '''port'''
|-
|| 02:31
|| 3. Upload the '''FLOSS firmware'''
|-
|| 02:34
|| That is, in the '''Arduino IDE''', upload the file available at '''Origin slash tools slash floss hyphen firmware slash floss hyphen firmware dot ino'''

|-
|| 02:49
|| As discussed in the earlier tutorial the above steps have to be done before proceeding further.
|-
|| 02:57
|| By default, '''Scilab '''does not have the capability to communicate with '''Arduino'''.
|-
|| 03:04
||  All such '''add-on functionalities''' are added to '''Scilab''' using the '''toolbox'''.
|-
|| 03:11
||  These '''functions''' are required to run various experiments on the '''Arduino Uno board.'''
|-
|| 03:18
||  It also establishes a '''serial communication''' with '''Arduino'''.
|-
|| 03:24
||  We have created different '''toolboxes''' for '''Windows''' and '''Linux OS.'''
|-
|| 03:30
|| The '''Scilab Arduino toolbox''' can be found inside the '''Origin slash tools slash scilab slash windows''' or '''Origin slash tools slash scilab slash linux'''  directory.
|-
|| 03:48
|| First we have to load the '''toolbox''' depending upon your '''OS'''.

|-
|| 03:54
|| I’ll show you how to load the '''toolbox''' in '''Linux'''.
|-
|| 03:59
|| Open the '''terminal''' by pressing '''Ctrl+Alt+T''' keys.
|-
|| 04:05
|| I have already installed '''Arduino IDE''' and '''Scilab 5.5.2''' in my '''Linux''' system as specified in the book.
|-
|| 04:16
|| Go to the folder where '''Scilab''' is installed as shown and launch '''Scilab.'''
|-
|| 04:27
||Next we have to change the '''working directory'''.
|-
|| 04:31
|| In the''' File Browser,''' select the '''toolbox''' folder available at '''Desktop slash Origin slash tools slash scilab slash linux'''
|-
|| 04:45
|| Click on the '''OK''' button.

|-
|| 04:48
|| Now the '''Scilab working directory''' becomes the '''toolbox''' folder.
|-
|| 04:54
|| In the '''file browser panel''', we can see the '''builder.sce '''file gets loaded.

|-
|| 05:01
|| This shows that we are in the right '''directory'''.
|-
|| 05:05
||Type the '''command exec builder.sce''' on the '''Scilab console'''.

|-
|| 05:13
|| Next, type the '''command exec loader.sce'''. This will load the '''toolbox'''.

|-
|| 05:23
|| '''Note''': If you clear the '''workspace''' for any reason, you will have to '''execute''' this '''command''' once again.
|-
||05:32
||We have to run the '''Scilab script''' to check whether the '''firmware''' is properly installed or not.

|-
|| 05:40
|| It is available at: '''Origin slash tools slash scilab slash test underscore firmware dot sce'''
|-
||05:49
|| In the '''Scilab console''', type '''editor''' and press the '''Enter''' key.

|-
|| 05:56
|| Click on the “'''File'''” menu and choose “'''Open'''”. 

|-
|| 06:00
|| Browse to the '''directory Origin slash tools slash scilab.'''

|-
|| 06:06
|| Choose the file '''test underscore firmware dot sce.'''
|-
|| 06:12
|| It will open a '''Scilab''' code.
|-
|| 06:15
|| In the '''menu bar''', click on the '''Execute '''option, to '''execute''' the code.

|-
|| 06:21
|| Then choose '''File with no echo'''.
|-
|| 06:24
|| We see the '''response''' of this code as '''"answer is equal to ok"'''.

|-
|| 06;31
|| This confirms the working of the '''Arduino-Scilab toolbox'''.
|-
|| 06:36
|| Next let us run the '''Scilab program''' in chapter 5. That is, '''Interfacing a Pushbutton.'''

|-
|| 06:44
|| This '''program''' will read the '''status''' of the '''pushbutton''' and display it on the '''GUI'''.
|-
|| 06:51
|| Open the file available at '''Origin slash user hyphen code slash push slash scilab slash push hyphen button hyphen status dot sce'''
|-
|| 07:05
|| Click on the '''Execute''' button.
|-
|| 07:09
|| Press the '''pushbutton''' in the '''shield'''.

|-
|| 07:13
|| The '''GUI''' in '''Scilab''' shows the status of the '''pushbutton''' as '''1''' when it is pressed.

|-
|| 07:20
|| It shows '''0''' when it is released.
|-
|| 07:24
|| Likewise practice the experiments in '''Scilab''' with other components as specified in the book.
|-
|| 07:32
|| Next we will see how to run the '''Arduino program''' in '''Xcos'''.
|-
|| 07:38
|| Type '''Xcos''' in the '''editor''' to launch  '''Xcos'''.
|-
|| 07:44
||Next we will run the code to turn the '''LED on''' or '''off''', depending on the '''pushbutton'''.

|-
|| 07:52
|| The code is available in the '''Origin slash user hyphen code slash push slash scilab slash led hyphen push hyphen button dot zcos'''

|-
|| 08:05
|| Click on the '''File''' menu and Open the file '''led hyphen push hyphen button dot zcos''' as shown.

|-
|| 08:15
|| When the '''user''' presses the '''pushbutton''', the '''LED''' on '''digital pin 9''' of the '''shield''' is switched '''on'''.
|-
|| 08:23
|| When the '''pushbutton''' is released, the '''LED''' is switched '''off'''.
|-
|| 08:29
||Do the other'''Xcos''' experiments as specified in the book.
|-
|| 08:35
|| Points to remember:

Whenever you plug the '''Arduino Uno board''' into the computer, check for the '''port'''.
|-
|| 08:44
|| Then '''execute''' the '''commands''' required for '''read-write permission'''.
|-
|| 08:49
|| Don’t upload any '''Arduino program''' after uploading the '''FLOSS firmware''' to '''Arduino Uno board.'''
|-
|| 08:57
|| This would overwrite the '''FLOSS firmware'''.
|-
|| 09:01
|| Check if the '''Arduino-Scilab toolbox''' is properly '''running''' or not.
|-
|| 09:07
|| You have to load the '''Arduino Scilab toolbox '''each time when you launch '''Scilab'''.
|-
|| 09:14
|| With this we come to the end of this tutorial. Let us summarize.
|-
|| 09:20
|| In this tutorial, we learnt about
