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

'''Learning Objectives'''
|| In this tutorial, we will learn about
*'''Arduino Julia''' toolbox
*Interfacing '''Arduino''' with''' Julia'''
|-
|| '''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'''
|-
|| '''Point to the book in the desktop'''
'''and open the book'''
|| I have downloaded '''Microcontroller Programming with Arduino and Julia '''e-book on my desktop.
|-
|| Show the relevant pages in the book.

Chapter 3 : Page 18, 25
|| 
*Refer to chapter 3 in the book.
*Follow the steps and do the installation of '''Arduino IDE '''and''' Julia '''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
|-
|| '''Slide 6:'''

'''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 Arduino-Julia''' toolbox
|| 
* By default''', Julia''' does not have the capability to connect to '''Arduino'''. 
* All such add-on functionalities are added to '''Julia''' using the toolbox.
* These functions are required to run various experiments on the Arduino''' Uno board.'''
* It also establishes a serial communication with '''Arduino'''.
|-
|| 
|| The '''Arduino Julia '''toolbox can be found inside the''' directory'''

'''Origin/tools/julia/ArduinoTools.jl'''
|-
|| 
|| Open the terminal by pressing '''Ctrl+Alt+T''' keys.

I have already installed '''Arduino IDE''' and '''Julia1.6.0''' in my '''Linux''' system as specified in the book.
|-
|| Cd Desktop/'''Origin/tools/julia'''

> julia '''test_firmware.jl''' 
|| In the terminal, go to the directory where the Julia toolbox is available.

Next, we have to load the '''Arduino-Julia '''toolbox.

Type the command as shown to execute the firmware.

We can see three "ok" messages.

This shows that the''' FLOSS-firmware''' and '''Arduino''' '''Julia toolbox''' are working properly.
|-
|| Show chapter 7
7.4.2
|| Next let us run the '''Julia''' program in chapter 7. That is, '''Interfacing a Potentiometer.'''

This program will turn on '''LEDs''' depending on the '''potentiometer''' threshold .
|-
|| 

>cd orgin/user-code/pot/julia
|| Switch back to the terminal.

Let us go to the folder where the''' pot-threshold.jl '''program is saved.
|-
|| > julia pot-threshold.jl
|| Type the command as shown to execute the program.
|-
|| '''Video: (required)'''
|| Rotate the knob of the potentiometer in the shield.

Observe the change in the color of the RGB LED.

The corresponding threshold values are displayed on the terminal.
|-
|| 
|| Do the other '''Julia''' experiments as specified in the book.
|-
|| '''slide 8:'''

'''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 Julia '''toolbox is properly running or not.
|-
|| 
|| With this we come to the end of this tutorial. Let us summarize.
