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

'''Learning Objectives'''
|| In this tutorial, we will learn about
* '''Arduino OpenModelica''' toolbox
* Interfacing''' Arduino '''with''' OpenModelica'''
|-
|| '''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 OpenModelica'''
|| If you are not familiar with '''OpenModelica, '''go through the''' spoken tutorials''' on this website.

You will learn about
* Introduction to '''OpenModelica'''
* '''OpenModelica '''interface
* Various perspectives and
* Simulation
|-
|| '''Point to the book in the desktop'''
'''and open the book'''
|| I have downloaded the ebook on my desktop.

Let us open the book '''Microcontroller Programming with Arduino and OpenModelica.'''
|-
|| Show the relevant pages in the book.

||
* Refer to chapter 3 in the book.
* Follow the steps and do the installation of '''Arduino IDE '''and '''OpenModelica '''depending upon your '''OS.'''
* Installation steps are given for '''Windows''' and '''Linux OS.'''
* 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
|-
|| '''Points to be noted:'''
'''Show 3.1.5 in the book, page 25'''
|| 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 9:'''

'''About Arduino-OpenModelica toolbox'''
||
* By default, '''OpenModelica '''does not have the capability to connect to '''Arduino'''.
* All such add-on functionalities are added to '''OpenModelica''' 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 different toolboxes for '''Windows''' and '''Linux''' OS.
|-
||

Show the directory
Desktop /origin/tools
||
The '''Arduino-OpenModelica''' toolbox can be found inside the''' '''directory
* '''Origin/tools/OpenModelica/windows/ or'''
* '''Origin/tools/OpenModelica/linux/'''

|-
||
|| First we have to load the toolbox depending upon your OS.

I’ll show how to load the toolbox in '''Linux'''.
|-
||
|| Open the terminal by pressing '''Ctrl+Alt+T''' keys.

I have installed '''Arduino IDE''' and '''OpenModelica 1.1.7 '''in my '''Linux''' system as specified in the book.
|-
|| cd Downloads

> OMEdit
|| Go to the folder where '''OpenModelica''' is installed as shown and launch the '''OpenModelica.'''

Next, we have to load the '''Arduino OpenModelica''' toolbox.

Click on '''File''' and then click on the '''OpenModel/Library File(s)''' option.

Navigate to '''Origin/tools/openmodelica/linux.'''

Select '''Arduino.mo '''and '''test_firmware.mo '''and click '''Open'''.

In '''OMEdit''', under the '''Libraries''' panel, look for three new libraries.

They are '''Arduino, Modelica_Synchronous, Modelica_DeviceDrivers and test_firmware.mo.'''

This confirms that the '''Arduino OpenModelica''' toolbox has been loaded successfully.
|-
|| Show chapter 8

||Next let us run the '''OpenModelica''' program in chapter 8. That is, '''Interfacing a Thermistor.'''

This program will read and display the thermistor values.

Switch back to the '''OmEdit '''interface.

The codes are available inside the''' Arduino OpenModelica''' toolbox''' '''under the libraries panel.

Select '''Arduino -> SerialCommunication -> Examples -> thermistor -> therm_read'''.

Double click on the file to open.

Click on the '''simulate''' button on the top right corner.

Click on the '''ok '''button in the simulation setup window.
|-
||
||We can see the thermistor value displayed on the screen.

Rub the thermistor with the fingertips.

It will transfer heat from the person's finger, thereby raising the temperature of the thermistor.

Accordingly, we can observe the change in the thermistor values.
|-
|| '''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-OpenModelica '''toolbox is properly running or not.
* You have to load the '''Arduino OpenModelica toolbox '''each time when you launch the '''OMEdit'''.
|-
||
|| With this we come to the end of this tutorial. Let us summarize.
|-
||

Slide 8:
