|-
|| '''Visual Cue'''
|| '''Narration'''
|-
|| '''Slide 1'''

'''Title Slide'''
|| Welcome to the Spoken Tutorial on '''Display Text on LCD''' using '''Electroblocks'''.
|-
|| '''Slide 2'''

'''Learning Objectives'''
|| In this tutorial, we will learn how to,
* Build a set of blocks to Display Text on LCD
* Check the output of the experiment using the simulator
|-
|| '''Slide 3'''

'''System requirements'''
|| To record this tutorial, I am using:
* Ubuntu Linux OS version 22.04
* ElectroBlocks application
* Google Chrome web browser

A working internet connection to use '''ElectroBlocks'''.
|-
|| '''Slide 4'''

'''Prerequisites'''

'''https://spoken-tutorial.org'''
|| To follow this tutorial, learner should have a basic knowledge of
* Electroblocks interface
|-
|| Open Google Chrome browser.

In New Tab, type

[https://electroblocks.org/ https://electroblocks.org/] '''

Point towards Default Blink LED circuit.
|| Let us open the Electroblocks platform on Google Chrome.

In the address bar type this url and press Enter to open the Electroblocks interface.
|-
|| Click on the '''New File/Blank file''' option available on the toolbar.

A pop-up window will appear on the screen.

Click on the '''OK''' button to start a new project.
|| Let us open a new blank file.
|-
|| Main video

Click on '''Add-ons'''

Click on the '''LCD screen''' option.

Select''' Setup LCD '''block

Point to the LCD screen in the circuit.
|| Let us create a '''Display text on an LCD''' project.

Click on the '''Add-ons '''menu available on the left hand side of the screen.

Click on the '''LCD screen''' option.

Select the''' Setup LCD block '''and drag it to the working area.

This '''block''' activates the '''LCD''' '''screen''' in the circuit.
|-
|| Point to''' memory type'''

Point to '''0x3F'''

Point to '''0x3F'''

Point to '''0x27'''

Select the 0x27 .
|| By default the '''memory type''' is '''0x3F''' in the '''Setup LCD Block'''.

'''0x3F''' is an '''I2C''' address.

'''I2C''' stands for '''inter-integrated circuit.'''

The '''I2C address''' is a unique identifier for communication.

Click on the dropdown option and select a suitable I2C address for your LCD screen.

If the LCD chip is from NXP Semiconductors manufacturer, its I2C address is 0x3F.

If the LCD chip is from a Texas Instruments manufacturer, its I2C address is 0x27.

In my case, I used the I2C address 0x27.
|-
|-
|| Point to '''size''' in '''lcd setup block'''

'''Point to 16x2'''

'''Only narration'''
|| By default the size of the LCD display is 16 by 2 ('''16x2). '''

16 represents the number of columns on the screen.

2 represents the number of rows on the screen.

Click on the dropdown option.

The platform also offers a 20x4 LCD display option.

A '''20x4 '''display can print 20 characters per row across four rows.

For this project I have selected a 16x2 LCD display.
|-
|| Point to '''SDA'''

Only narration

Point toward connected''' pin#'''

Point to '''SCL'''

Only narration

Point toward connected''' pin A5'''
|| In '''I2C''' LCD display, '''SDA''' stands for '''Serial data line.'''

The '''Serial Data Line''' carries the data between the '''arduino''' and the '''LCD'''.

By default, the '''SDA''' line of the '''LCD''' is connected to the '''A4''' pin of the '''Arduino'''.

'''SCL''' stands for '''Serial Clock Line.'''

The '''Serial Clock Line''' synchronises the data transmission.

The '''SCL '''line of the '''LCD''' is connected to the '''A5''' pin of the Arduino.
|-
|| Only narration

Click on the '''LCD screen '''

Drag and drop the '''Print-> Delay-> Clear''' block inside the loop block.

Point to the block in the loop.
|| Now we will add an '''LCD''' Screen.

Click on the '''LCD screen''' option.

Drag and drop the '''Print-> Delay Clear''' block inside the loop block.

This block allows you to display words or numbers on any row of the LCD.
|-
|| Click on the '''Print on Row 1 text Block''', type “'''Hello All”'''.

Press '''Enter'''

Click on the '''Print on Row 2 text block''', type “'''This is LCD'''”

Press '''Enter'''.

Point to delay in print delay clear block.

Only narration.
|| Click on the '''Print on Row 1 text block''', type “'''Hello All”'''.

Press Enter to save the changes made in the block.

Click on the '''Print on Row 2 text block''', type “'''This is LCD'''”

By default the '''delay''' of '''3 seconds''' is shown at the end of the block.

This block displays the text for 3 seconds.
|-
|| Only narration

Duplicate the '''Print Delay Clear''' block

Only narration

Drag and place this block below print delay clear block

Click on the '''Print on Row 1 text block''', type “'''I will display'''”

Press enter

Click on the '''Print on Row 2 text block''', type “'''text on screen'''”

Press enter
|| Right click on the '''Print Delay Clear '''block and select the '''Duplicate''' option.

This action creates an identical block in the working area.

Drag and place this block below '''print delay clear''' block

Click on the '''Print on Row 1 text block''', type “'''I will display'''”

Press '''Ente'''r to save the changes.

Click on the '''Print on Row 2 text block''', type “'''text on screen'''”

Press '''Enter''' to save the changes.
|-
|| Only Narration.

Click on '''Code''' '''Icon.'''
|| Now, we will see the '''arduino''' '''code''' generated by '''electroblocks'''.

Click on the '''Code''' '''icon'''.
|-
|| Highlight '''<nowiki>#include <Wire.h></nowiki>'''
|| This library is required for I2C, that is (Inter-Integrated Circuit) communication.
|-
|| Highlight''' #include <LiquidCrystal_I2C.h>'''
|| This library handles communication between the Arduino and the LCD Screen.
|-
|| Highlight '''LiquidCrystal_I2C lcd(0x27,2,16);'''

Point to '''0x27,2,16'''
|| This command creates an lcd object, which represents the LCD screen.

'''0x27''' is the '''I2C address''' of the '''LCD'''.

'''2''' represents the number of rows.

'''16''' represents the number of columns on the screen.
|-
|| Highlight '''Void''' '''Setup loop'''

Highlight '''lcd.init()'''

Highlight '''lcd.backlight()'''
|| The '''Void Setup''' function runs once when the '''Arduino''' starts.

It initialises the LCD screen, making it ready for use.

This command turns on the LCD screen backlight, which improves visibility.
|-
|| Highlight

'''Void loop()'''
|| The '''Void loop() '''function shows actions performed by '''components''' and '''sensors''' in the experiment.
|-
|| Highlight

'''lcd.clear();'''

'''lcd.setCursor(0, 0); '''
|| This command is used to clear the screen.

This command sets the cursor to the first column, first row.
|-
|| '''lcd.print(String("Hello All")); '''

'''lcd.setCursor(0, 1); '''

'''lcd.print(String("This is LCD")); '''
|| This command Prints "Hello all" on the first row.

This command sets the cursor to the first column, second row.

This command prints "'''This is LCD'''" on the second row.
|-
|| '''Highlight'''

'''delay(3000); '''

'''Highlight'''

'''lcd.clear(); '''
|| This command makes sure the above result is visible for 3 seconds on the LCD screen.

'''lcd.clear(); '''

This command clears the screen after the delay.
|-
|| '''Highlight'''

'''lcd.setCursor(0, 0); '''

'''Highlight'''

'''lcd.print(String("I will display")); '''

'''Highlight'''

'''lcd.setCursor(0, 1); '''

'''Highlight'''

'''lcd.print(String("text on screen")); '''
|| This command sets the cursor to the first column,first row.

This command Prints "I will display" on the first row.

This command sets the cursor to the first column, second row.

This command Prints "text on screen".
|-
|| '''delay(3000); '''
|| This command makes sure the above result is visible for 3 seconds on the LCD screen
|-
||
|| We shall first check the desired result using the simulator.
|-
|| Click on Home page

Click on the Play button
|| Click on the '''Home page''' option from the toolbar.

Click on the '''Play''' button to start the simulation.
|-
|| Point to simulation window.

Point to the display.

Only narration
|| We will see the visual representation of the simulation.

"Hello All" and "This is LCD" are displayed for 3 seconds on the LCD screen.

Next, "I will display text on screen" is shown for another 3 seconds.

Then the screen is cleared.
|-
|| '''Slide 5'''

'''Summary'''

In this tutorial, we learnt about:
* Build a set of blocks to Display text on LCD
* Check the output of the experiment using the simulator
|| This brings us to the end of this tutorial.

Let us summarise.
|-
|| '''Slide 6'''

'''Assignment'''

* Write your name, class and roll number on the LCD screen with a 5 second delay.
|| As an assignment, please do the following.
|-
|| '''Add the Assignment video.mp4 in the main video with 10.27 timestamp.'''
|| Notice the output of the assignment shown in the video.
