Arduino Digital Bday

Starting by Introducing who we are.

Now I need participant to start engaging with me so I will ask them a question to ensure that.

• I don’t need them to answer this correctly just a way to open the discussion.

• I have done this in a way asking them about the board name then the age of the board.
• The pictures are to help them to answer correct.

So this is the Arduino board and this year mark the 20 Anniversary.

Its Important for them to understand that Arduino is an open source platform which have a compatible hardware support their software.

The question now (How do you think they are celebrating this day)

• They usually celebrate through making workshops and events to support knowledge sharing and reveling latest technology done by them.

Now why all of this is happening, why do you think this piece of hardware is important?

For the participant to understand the importance of this board they need to understand the difference between a normal computer and a microcontroller.

• Here we need to let them know that this small piece can act as a full computer able to gather data, process, and act depends on the code.

Now we need to link between Ideas and how this board made them real (Tangible).

• I will show them a video demonstrating a full working machine powered by Arduino.

Lets start showing them what they will do today

Then I will list the needed parts they will be using.

Now I will be explaining each part aside.

Then I will explain the term simulation and why we need such process in this field.

I will start by explaining how to access the platform (TINKERCAD)

Then How to sign up.

How to sign in

Class Room code if they are not welling to create or they don’t have.

Then How to create a new project.

Now we can start adding the component and wiring them up.

First step we need to search the component and place it in the working area.

I will start by picking the Microcontroller (Arduino UNO)

Then I will pick the piezo buzzer

Finally the LCD

At this point I need to create the connection between the component (Wiring)

I will start with the Buzzer

• Let them choose there own wire color but make sure to let them know that we mostly use the red for +V and the Black for the (GND)

• Finally the LCD
• Make sure to let them know that for the Arduino UNO we have two places to connect the I2C but we only have one channel not 2 so that mean if you want to connect more than one device you will a Multiplexer.

We need to open the coding section in the platform (TINKERCAD)

Here we have the coding section and you can toggle between coding styles (Blocks, Block+Text, and text)

• Remember that between block and block+text its fine the code are going to be saved but if you toggle between blocks and text it won’t save the code you will loose all your code.

Now lets start with the on start loop –> Which is the loop are going to be executed once (Setup Loop) when the MCU start working.

Then we need to initialize the LCD

Make sure her to match the address with the LCD address and also the type.

Now lets code the forever loop

Lets write something on the LCD like (Happy birthday Arduino)

• We choose the set position function to set the cursor in order to write on the LCD column and row (Specifically)
• Print on LCD just to write

This is how its gonna look like

Now we will code the buzzer

• The code is gonna look very simple now as we are only gonna change the delay and the note

Now its just a matter of having the same code just changing the tone and the delay in between

Until the end of the code

I will share the code in the attachment section also I will add a pictures here for each section of the code.
