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)

Pomodoro light-sound system. It is a smart electric circuit with an RGB LED and a buzzer. It applies special sound and light suitable for studying for the Pomodoro time you set via a GUI. It applied different sound and light effects during the break time.

This project is inspired by the functions of a smart home that matters to me.

Tool Chain

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

Softwares

Tinkercad

Arduino IDE

Android GUI

PowerPoint

Tools

Arduino UNO - USB cable

buzzer - RGB LED - bread board - HC-05 Bluetooth module - 4 330 Ohms resistances - 1 1K Ohms resistance

male-male jumper wires

Multimeter

5V power adapter

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?

Stage 1: Tinkercad circuit

prepare all the needed components (Piezo buzzer - RGB LED - 3 330 Ohms resistances)

wiring

Add resistances suitable for the voltage divider connection of the Bluetooth module.

Stage 2: Power Point

we use a screenshot of the Tinkercad circuit and a picture of the electronic component that is not found in Tinkercad (HC-05 Bluetooth module).
Use this background remover to remove the white background and insert the pictures in a PowerPoint slide.
Complete the wiring using lines from Insert menu.

Stage 3: Arduino code

write a simple code to check Bluetooth module with serial monitor

buzzer checker simple code

write a code with all light features
to construct a music code, we need to use pitches.h (It is NOT A LIBRARY).

Here, I used an example that has pitches.h included. then delete all the code in toneMelody and paste the music code I want. Besides editing the buzzer pin number and delete any unwanted code lines from the reference.

Note: in the pitches.h tap, we add the 3define REST 0000 line

Super Mario Break melody code

Harry Potter study melody code.

Final code

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?

Stage 1: Construct and check each component separately

Check the buzzer with a simple alarm tone.
Check Harry Potter music without a Bluetooth module
Check Super Mario music without a Bluetooth module

Check the Bluetooth module with serial monitor.

Check all the light features light a Bluetooth module.

Stage 2: Construct the final circuit

Build the circuit.

When connecting to electric current, Connect your phone Bluetooth to our Bluetooth module.

from phone GUI, connect to our Bluetooth module

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)

An error appeared in the tone that has REST melody because it is not defined in the pitches.h tap

>> we defined it manually

Final Project

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

How to connect and code a Bluetooth module, and the method of constructing the code in many parts then collecting them together in one code has helped me alot in this project.

WOW!

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

Connecting the Bluetooth module with voltage divider.
