|-
|| '''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.

*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.'''
|-
|| Arduino shield_USB.jpg
|| 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 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.

'''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.
