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)

This week's assignment was to communicate wirelessly with a Smart Circuit via a Graphical User Interface (GUI) by

-building a simple smart circuit that contains at least TWO action components that could be controlled wirelessly.

-using either the Android GUI or PC GUI to control the action components.

I want to make an ambulance serin.
It's a light and sound, the light is red and blue that switches in a sequence, and a buzzer.
I will use a smartphone app to control this serin as input.

Tool Chain

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

Software: Fritzing

To simulate the circuit

Software: Arduino IDE

To write the code and upload it to the Arduino UNO

To Control the circuit wirelessly.

Materials:

Mini Breadboard
Arduino UNO
cables
220-ohm resistors
Jumpers
Buzzer sensor
RGB LED
Bluetooth Module

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?

First, I tried to make the circuit and simulate it on tinker cad.
Wired the buzzer sensor and RGB led to the Arduino to digital pin and GNDs.

Wired the Bluetooth module TX as output (pin 0), RX as input (pin 1), gnd, and 5v.

I used the Arduino IDE to write the code and made it 3 parts for 3 modes.
I have set the Arduino to read the inputs and outputs from the App.

I had defined the RGB led pins and the buzzer sensor and the incoming data from the mobile app.

then, in void setup defined the RGB led and buzzer sensor as outputs and let serial begin at speed 9600.

In void loop, I made an if condition that if the incoming data = 1, set the RGB led to the red and the buzzer to tone 800.

If incoming data = 2, set RGB led to blue and the buzzer to tone 900.

If incoming data = 3, set RGB led to light red then blue and the buzzer to tone 800, 900 in sequence to show the serin of the ambulance.

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?

I started to build the circuit on the breadboard and Arduino UNO.
Connect the buzzer sensor and the RGB led with the Arduino to digital pins A0, 3,6,5 respectively and GNDs, as output components.
Wired the Bluetooth module TX as output (pin 0), RX as input (pin 1), gnd, and 5v.

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?

I asked Ibrahim about wiring the Bluetooth module with resistors and he suggested not using any resistor like in EOW activity.

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?

When I got stuck I go to google and YouTube videos to get inspired by their ideas on how to make the buzzer sensor make the tone of an ambulance.

Final Project

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

I think this assignment will help me a lot when I started my final project, it helped me understand how could insert lights and sirens and control them through a mobile app.
And. I want to add this feature to my RC car.

WOW!

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

The coolest thing I have learned this week is how to use the Bluetooth module HC05that uses to connect a mobile app to the arduino.
