Week 8

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 week's idea is to control things remotely via Bluetooth or something else.

I've always loved music, especially the little games that simulate the piano or guitar or something like that, so I thought why not make a small device that can be controlled via Bluetooth through an application on the phone

Tool Chain

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

I will use Tinkercad to simulate the circuit before you send it to the breadboard

I will use the Arduino IDE to upload the code to the Arduino

Arduino blue-control App on the mobile phone to control the Buzzer

For the electrical circuit

Jumper Wires.

Arduino

Bluetooth module hc05

Buzzer to make a sound

Small breadboard: To connect the circuit.

Adaptor 9V :The source of electricity.

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?

My idea is to control the alarm clock through the phone via Bluetooth to play certain notes to simulate children's games that play music.

I started by connecting the positive and negative of the Arduino to the vertical lines on the board.

Then connecting the TX to the RX of the Arduino and the RX to the TX of the Arduino.

I connected the Bluetooth positive and negative to the Arduino positive and the negative on the board.

Then I connected the Buzzer and put its negative leg on the same line as the negative leg of the Arduino and connected a wire from the pin I had identified to its positive leg.

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?

Coding

I first started by defining the library that I would need for the Buzzer

Then I defined a variable that I would need to store inputs from the user

Then I defined some variables and set values for them that I would use to give commands to the buzzer to play a specific note.

As for the notes to make good sounding notes I went back to this tutorial and understood the code, then took the numbers I needed from it to play the notes.

I set the begin at (9600)

As for the set-up, I define the pin buzzer as an OUTPUT to controller using Arduino.

For the loop, I used while (Serial.abailable()) so if there is no user input the Arduino will print nothing.

Then I used the variable I created to store the readings from the user.

Then I started with the first condition, which is if the input is equal to 1, play the specified note.

I repeated the same thing with the rest of the conditions, changing the notes played.

In the end, I used Serial.println (userInput) to print the user input on the serial monitor.

Circuit connection

I pulled out all the components I would need.

I started connecting the positive and negative of the Arduino to the board.

Then I wrapped the wire around itself because it was long and I didn't want it to get in the way.

Then I connected the Buzzer and put its negative leg on the same line as the negative leg of the Arduino and connected a wire from the pin I had identified to its positive leg.

I put Bluetooth on the board and then I connected the Bluetooth positive and negative to the Arduino positive and the negative on the board.

Then connecting the TX to the RX of the Arduino and the RX to the TX of the Arduino.

And here is my final outcome

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?

Working with my teammate Farah to do the task of the week helped me a lot.

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?

The problem I faced this week was after uploading the code to the Arduino and after I connected the circuit to the board and to the Arduino, I connected it to the 5-volt adapter, but it did not work. At first, I thought there was a wrong connection or something, but there was no such thing. After thinking about it, I tried to connect it to the 9-volt adapter and it worked, so you should connect it to a 9-volt adapter and not a 5 volt one Because the Bluetooth module needs 5V to work

Final Project

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

What I learned this week about controlling things remotely via Bluetooth or other, and it gave me new experience that I might need if I wanted to add remote control via Bluetooth

WOW!

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

The best thing this week is making a robot arm and controlling it to catch fish.

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.

I didn't design anything new, but I modified the design this week.
