Week 8- 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)

Idea: " smart home music"

Through Bluetooth, when the Arduino receives 1 , infrared is on and buzzer works and servo motor rotates
when the Arduino receives 2 , buzzer is off and servo motor stop
The servo should move a welcome message to the person entering the house in addition to music from buzzer

Tool Chain

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

Software :

Tinker CAD:

for circuit simulation and connection of items

Arduino IDE:

For coding and uploading code on real Arduino board

Components:

Arduino UNO board
slider switch
breadboard
jumpers
IR sensor
Servo motor
Buzzer
connecting cable (from Arduino board to laptop)

Tinker cad components

Real circuit components

Breadboard

yellow LED

IR sensor

slider switch

Jumpers

Servo motor

Arduino UNO

connection cable

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?

Tinker cad Connection

Code blocks "as an initial guide "

Design Phase:The design of the circuit is so simple:

IR sensor ,Servo motor, buzzer on a breadboard connected with Arduino UNO board

Input component:

Slide switch

IR sensor

Action component:

Servo motor

buzzer

CODEBLOCKS Phase:

As a guide for the required code, I started with code blocks:

Slider switch on pin 8 "input"
Connected servo motor to Pin 9"output"
connected IR sensor to pin 2"input"
Buzzer on pin 3 "output"
IF .. Else condition to control slider switch (on and off), when on:

Servo moves
Buzzer works

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?

Implementing Circuit on breadboard

After making the required connections on tinker cad and simulating the circuit. I built connection on breadboard.

Implementing The Code:

After making the required connections on tinker cad and simulating the circuit. i copied the text code to Arduino IDE
I completed the code by adding extra movement for servo
I set code lines for Bluetooth receive
I removed switch condition as it was a bit useless.

I used this app to send the numbers

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

Feedback:

from Saeed:

check the code as i missed if condition in a line

From Sherif:

replace LED with Buzzer

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

I had problems connecting Bluetooth module, especially voltage divider.
Ahmed Saeed helped me through some photos from real breadboard.
the Bluetooth module worked.

Bluetooth Module

Final Project

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

Title of Media

Good trial as in i want to use a slider on mobile to control servo angle
helped me understand user interface of final project

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

Different applications of servo motor
