|| '''VISUAL CUE'''
|| '''NARRATION'''
|-
|| '''Slide 1:'''
||Welcome to the Spoken tutorial on '''Arduino Programming with Scilab and Xcos.'''
|-
|| '''Slide 2:'''

'''Learning Objectives'''
|| In this tutorial, we will learn about
*'''Arduino - Scilab toolbox'''
*Interfacing '''Arduino''' with '''Scilab'''
*Interfacing''' Arduino '''with '''Xcos'''

|-
|| '''Slide 3:'''

'''System requirements'''
|| To record this tutorial, I’m using
*'''Ubuntu Linux '''OS version 18.04 
*'''Arduino Shield''' and
*'''Arduino Uno Board'''

|-
|| '''Slide 4:'''

'''Prerequisites'''
||To follow this tutorial, you should go through the below '''Arduino spoken tutorial.'''
* '''Getting ready for Arduino FLOSS.'''

|-
|| '''Slide 5:'''

'''Getting ready for Arduino Floss'''

|| In the above tutorial, you will learn
*How to download the '''e-book''' and code files required for the experiments.
*How to upload and '''compile Arduino programs''' in '''Arduino IDE.'''
*About '''FLOSS Firmware'''
|-
|| '''Slide 6:'''

'''About Scilab and Xcos'''
|| If you are not familiar with '''Scilab''', go through the''' Scilab spoken tutorials''' on this website.

You will learn about:
*Introduction to '''Scilab'''
*Introduction to '''Xcos'''
*'''Scilab''' and '''Xcos''' interface and
*'''Simulation''' 
|-
|| '''Point to the book in the desktop'''
'''and open the book'''
|| I have downloaded '''Microcontroller Programming with Arduino, Scilab and Xcos ebook'''.
|-
|| Show the relevant pages in the book.

||
* Refer to chapter 3 in the book.
*Follow the steps given for the '''installation''' of '''Arduino IDE '''and''' Scilab'''
*'''Installation''' steps are given for '''Windows''' and '''Linux OS.'''
*'''Xcos''' comes pre-installed with '''Scilab'''. Hence a separate installation of '''Xcos''' is not required.
* The experiments that are covered in the book are tested in '''Ubuntu Linux 18.04 '''and '''Windows 10 OS.'''

|| Connect the '''Arduino uno board''' with '''Arduino shield''' to the '''USB port''' of the computer
|-
|| '''Slide:'''
'''Points to be noted:'''
|| Note the below points:

1. Launch '''Arduino IDE'''

2. Check the '''port'''

3. Upload the '''FLOSS firmware'''

That is, in the '''Arduino IDE''', upload the file available at '''Origin/tools/floss-firmware/floss-firmware.ino'''

As discussed in the earlier tutorial the above steps have to be done before proceeding further.
|-
|| '''Slide 7:'''

'''About -Scilab''' '''- ArduinoToolbox'''
|| By default, '''Scilab '''does not have the capability to communicate with '''Arduino'''.
* All such '''add-on functionalities''' are added to '''Scilab''' using the '''toolbox'''.
* These '''functions''' are required to run various experiments on the '''Arduino Uno board.'''
* It also establishes a '''serial communication''' with '''Arduino'''.
* We have created different '''toolboxes''' for '''Windows''' and '''Linux OS.'''
|-
|| Show the directory in the book

|| The '''Scilab Arduino toolbox''' can be found inside the '''Origin/tools/scilab/windows''' or '''Origin/tools/scilab/linux'''
directory.
|-
|| 
|| First we have to load the '''toolbox''' depending upon your '''OS'''.

I’ll show you how to load the '''toolbox''' in '''Linux'''.
|-
|| Open the '''terminal'''

Go to the folder where '''Scilab''' is installed

|| Open the '''terminal''' by pressing '''Ctrl+Alt+T''' keys.
I have already installed '''Arduino IDE''' and '''Scilab 5.5.2''' in my '''Linux''' system as specified in the book.

Go to the folder where '''Scilab''' is installed as shown and launch the '''Scilab.'''
|-
|| 
||Next we have to change the '''working directory'''.
In the''' File Browser,''' select the '''toolbox''' folder available at '''Desktop/Origin/tools/scilab/linux'''

Click on the '''OK''' button.

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

This shows that we are in the right '''directory'''.
|-
|| > '''exec builder.sce'''

||Type the '''command exec builder.sce''' on the '''Scilab console'''.

Next, type the '''command exec loader.sce'''. This will load the '''toolbox'''.

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

It is available at:
'''Origin/tools/scilab/test_firmware.sce'''
|-
|| 
Select '''Origin/tools/scilab'''/ '''test_firmware.sce.'''

|| In the '''Scilab console''', type '''editor''' and press the '''Enter''' key.

Click on the “'''File'''” menu and choose “'''Open'''”. 

Browse to the '''directory Origin/tools/scilab.'''

Choose the file '''test_firmware.sce.'''

It will open a '''Scilab''' code.
|-
|| Click on the '''Execute '''

Select''' File''' with '''no echo'''.

|| In the '''menu bar''', click on the '''Execute '''option, to '''execute''' the code.

Then choose '''File with no echo'''.

We see the '''response''' of this code as '''“ans = ”“ok”''' three times.

This confirms the working of the '''Arduino-Scilab toolbox'''.
|-
|| Show chapters 5 program '''push-button-status.sce'''

|| Next let us run the '''Scilab program''' in chapter 5. That is, '''Interfacing a Pushbutton.'''

This '''program''' will read the '''status''' of the '''pushbutton''' and display it on the '''GUI'''.
|-
|| Open the file '''Origin/user-code/push/scilab/push-button-status.sce'''
|| Open the file available at '''Origin/user-code/push/scilab/push-button-status.sce'''
|-
|| Click on '''Execute''' 
|| Click on the '''Execute''' button.

Press the '''pushbutton''' in the '''shield'''.

The '''GUI''' in '''Scilab''' shows the status of the '''pushbutton''' as '''1''' when it is pressed.

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

The code is available in the '''Origin/user-code/push/scilab/led-push-button.zcos'''

Click on the '''File''' menu and Open the file '''led-push-button.zcos''' as shown.

When the '''user''' presses the '''pushbutton''', the '''LED''' on '''digital pin 9''' of the '''shield''' is switched '''on'''.

When the '''pushbutton''' is released, the '''LED''' is switched '''off'''.
|-
|| 
||Do the other'''Xcos''' experiments as specified in the book.
|-
|| '''Points to remember:'''
|| Points to remember:
* Whenever you plug the '''Arduino Uno board''' into the computer, check for the '''port'''.
*Then '''execute''' the '''commands''' required for '''read-write permission'''.
*Don’t upload any '''Arduino program''' after uploading the '''FLOSS firmware''' to '''Arduino Uno board.'''
*This would overwrite the '''FLOSS firmware'''.
*Check if the '''Arduino-Scilab toolbox''' is properly '''running''' or not.
*You have to load the '''Arduino Scilab toolbox '''each time when you launch the '''Scilab'''.
|-
|| 
|| With this we come to the end of this tutorial. Let us summarize.
