TIME	NARRATION
00:01	Welcome to the Spoken tutorial on Arduino Programming with Scilab and Xcos.
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 otherXcos 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 Arduino - Scilab toolbox
09:27	Interfacing Arduino with Scilab
09:31	Interfacing Arduino with Xcos
