Week # 7- Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

This idea was based on preparatory work for the final project

So I used the LCD monitor and looked it up and found the attached video

Explanation file attached

And I took from them what I needed to prepare the project

Also attached is a picture of the idea code

The idea is:

2 buttons input and 2 output ( Lcd - buzzer )

the first button to play the sound after pressing it by buzzer .

And the second let the screen works And the word diploma appears and my name appears and disappears

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

I used Arduino IDE Software .

Tinkercad for building the circuit and simulating .

I uesd These materials :

Arduino Uno
Usb cable .
2 push buttons .
Buzzer .
Mini Breadboard .
LCD Liquidcrystal i2c .
Jumpers .
Cardboard .
Adaptor 9 V .

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

LCD File

I start software Arduino IDE

First i install A library for Liquidcrystal I2C LCD displays

after i watch videos

then create a wiring diagram by Tinkercad

I used the Arduino UNO board to control the input and output devices

My Idea has two input components with two action

first input : push button make the buzzer working play music

second input : push button : make the LCD show some words (maker diploma 23 - Naeem)

and Output : 1- LCD has a few words and 2- Buzzer making sound

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

Video File 1

Video File 2

The Arduino code (*.ino)

This part of the code demonstrates

Download screen library

and turn on the screen

And the definition of input units - 2 push button as input pullup

at Arduino pins 7 - 8

And also the definition of buzer pins 9 as output

The code is explained here

If the buttons on the Benz 7 were pressed

it plays music by the buzzer

The code is explained here

If the buttons on the Benz 8 were pressed

it make LCD screen show some words

then clear after 2 second

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

the challenges :

I faced a challenge when uploading the code to the Arduino

Writing does not appear on the screen

I made several attempts and thought there was an error in the code

Until I called a colleague diploma He advised me to:

Behind the screen, there is a lighting control that needs to change direction - until the writing appears

This actually happened and the words appeared

As shown in the attached three photos .

Another challenge:

when writing the code

When adding the screen code inside the pressed button code

I found a delay in executing the command of pressing the button

I found the solution after experimentation

Putting the screen code inside else

That is, when the button is pressed, the buzzer works.

And when you leave the button, the screen works

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

I will mainly use

screen in the final project

And I have been trained in this duty

to use it

and write its code

and change the words displayed on it

It contains two lines and 16 letters
