|| Let us see the content of the '''Origin''' folder.

Open the '''Origin''' folder.
* We can see the folders as'''tools''' and'''user-code.'''
* In the '''tools''' folder, we have given the '''toolbox''' required for various '''software'''.
* Follow the instructions given in the book on how to load the '''toolbox'''.
* In the '''user-code '''folder, all the '''codes''' required for various experiments are given here.

|-
|| 
|| In this tutorial, we will see how to '''run''' experiments on '''Arduino IDE.'''

I’ll open the '''python.pdf''' and show the various chapters of the book.

|-
|| Show the relevant pages in the book.

Chapter 3: Page 18, 19
|| 
* Refer to chapter 3 in the book that you have downloaded.
* Follow the steps given for the '''installation''' of '''Arduino IDE '''
* '''Install''' the '''Arduino IDE''' depending upon your '''OS'''
* The experiments that are covered in the book are tested in '''Ubuntu Linux 18.04''' and '''Windows 10 OS.'''
|-
|| Slide 6:

'''Arduino IDE''' installation:

|| You have to '''install Arduino IDE 1.8.13''' either in''' Linux''' or '''Windows OS.'''

Note that an '''internet connection''' is required to do the installation.

|-
|| 

About Shield

|| Next, let us see the picture of the '''shield'''.
* This is the '''shield''' developed by the '''FOSSEE''' team.
* It contains various components required for the experiments.
* It is already wired with the respective '''pin''' of '''Arduino Uno.'''
* It is a ready-to-use '''shield''' that can be used with only '''Arduino Uno '''

|-
|| 

About the experiments
Show the pages in the book
|| We will perform the below experiments using the '''shield'''.
# '''Interfacing a Light Emitting Diode'''
# '''Interfacing a Pushbutton'''
# '''Interfacing a Light Dependent Resistor'''
# '''Interfacing a Potentiometer'''
# '''Interfacing a Thermistor'''
# '''Interfacing a Servo Motor'''
|-
|| :

About the experiments
|| The next two experiments are performed without the '''shield'''.
# '''Interfacing a DC Motor'''
# '''Implementation of Modbus Protocol'''

|-
|| Show the image:
|| 

First, connect the '''shield''' to the''' Arduino Uno board'''.

Then connect the '''board''' to the '''USB port''' of the computer.
|-
|| 
|| Open the '''Linux terminal''' by pressing '''Ctrl+Alt+T''' keys simultaneously.
|-
|| Open the terminal
|| First we have to check the '''port''' on which the '''Arduino Uno''' is connected.
|-
|| Type

ls /dev/ttyACM*

Highlight '''ttyACM0'''

sudo chmod a+rw /dev/ttyACM0
|| Type the below '''command'''.

In my case, the '''port''' is '''ttyACM0'''.

Please note down the '''port''' in your system.

Type the '''command''' as shown to give the '''read, write permission''' to the '''port'''.

Enter the '''system password''' if prompted

This '''command''' has to be executed each time when you connect the '''Arduino board''' to the computer.
|-
|| '''> cd '''''opt''/arduino-1.8.13

>./arduino
|| 

I have already installed '''Arduino IDE''' in my system as specified in the book.

Follow the steps as shown in chapter 3 and launch '''Arduino IDE'''.

'''Arduino IDE '''opens as shown here.
|-
|| Select Tools>>port

Point to '''ttyACM0'''
|| Click on the '''Tools menu''' and select '''Port'''.

Make sure the '''port ttyACM0''' is selected.
|-
|| 

Show the chapter 4 heading and the program led-blue.ino
|| Let us test the working of the '''Arduino board''' with a simple '''program'''.

Let us check the experiment specified in chapter 4. That is, '''Interfacing a Light Emitting Diode.'''

This '''program''' will light the blue '''LED''' on the '''shield'''.
|-
|| Open the file
|| In the '''Arduino IDE''', open the file available at '''Origin/ user-code/ led/ arduino/led-blue/ led-blue.ino.'''
|-
|| Compile and upload 

Show the output

Blue led.jpg
|| '''Compile''' and upload the '''program'''.

Now we can see the blue '''LED''' is turned '''ON'''.

This shows the '''Arduino board''' and the '''shield''' are working correctly.
|-
|| Show the experiments in the book
|| Likewise, practice the other experiments with '''Arduino code''' that are specified in the book.
|-
|| 
|| Now we will learn how to connect '''Arduino''' with various '''FLOSS'''.
|-
|| '''Slide 8:'''

'''About FLOSS Firmware:'''
|| For this, we have to upload the '''FLOSS firmware''' on the '''Arduino Uno''' using '''Arduino IDE.''' 

This '''firmware''' is an '''Arduino''' file with '''.ino''' extension.
|-
|| '''Slide 9:'''

'''Why do we need FLOSS Firmware?'''
|| Why do we need '''FLOSS firmware'''?

This enables the communication between'''FLOSS''' and '''Serial port'''.

It will decode and execute the '''commands''' sent by other '''FLOSS'''.

For example '''FLOSS''' such as '''Python, Scilab, Julia, OpenModelica, etc.'''
|-
|| Open the file

'''Origin/tools/arduino-firmware/floss-firmware.ino'''

Point to the success message
|| Now we will upload the '''FLOSS firmware''' to the '''Arduino Uno.'''

In the '''Arduino IDE''', open the file available at'''Origin/tools/floss-firmware/floss-firmware.ino'''

'''Compile''' and upload the program.

We can see the '''success message''' at the bottom of the '''IDE'''.

It shows '''FLOSS firmware''' has been properly '''installed'''.
|-
|| '''Slide 10:'''

'''Points to remember:'''

|| '''Points to remember:'''
* Whenever you '''plug''' the '''Arduino Uno''' into the computer, check for the '''port'''.
* Then '''execute''' the '''command''' required for '''read-write permission.''' 
* Don’t upload any '''Arduino program''' after uploading the '''FLOSS firmware''' to '''Arduino Uno.'''
* This would overwrite the '''FLOSS firmware'''.
|-
|| 
|| With this, we come to the end of this tutorial. Let us summarize.
|-
||
