'''Title Slide'''
|| Welcome to the '''Spoken Tutorial''' on '''Smiley Generator''' using '''Electroblocks'''.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| '''Slide 2:'''

'''Learning Objectives'''
|| In this tutorial, we will learn how to,
# <div style="margin-left:1.27cm;margin-right:0cm;">Build a set of blocks to create a '''Smiley generator'''</div>
# <div style="margin-left:1.27cm;margin-right:0cm;">Check the output of experiment using the simulator</div>

|- style="border:1pt solid #000000;padding:0.176cm;"
|| '''Slide 3:'''

'''System requirement'''
|| To record this tutorial, I am using the following setup.
|- style="border:1pt solid #000000;padding:0.176cm;"

Drag and drop the '''Wait block for 0.2 second '''in the working area.

Place this block below the '''Led Matrix Draw''' block.

Change the time to '''1''' seconds in the block.
|| Now we have to make sure that the LEDs remain ON for a certain time.

For this, we must add a wait block.

Click on the '''Time''' section.

Drag and drop the '''Wait for 0.2 second block '''and place it below the '''Led Matrix Draw''' block.

Change the time to '''1''' second in the block.

|| We will turn OFF some LEDs to create an interactive smiley.

Right click on the '''Led Matrix Draw''' block and select the '''Duplicate''' option.

This action creates an identical block in the working area.

Place this block below the '''wait for 1 second''' block.

Let us uncheck a few of the checkboxes to create an interactive smiley.
