Week 08- 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)

Integrating Fire Alarm and HVAC Systems to Ensuring Safety

In the realm of modern building design and construction, the seamless integration of various systems is paramount to both occupant safety and operational efficiency. One critical yet often underappreciated facet of this integration is the coordination between fire alarm systems and HVAC (Heating, Ventilation, and Air Conditioning) systems. Properly aligning these two systems can be the linchpin that determines life and property protection in the event of a fire emergency.

Integration between fire alarm and smoke exhaust fan in emergencies.

Tool Chain

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

Software ,web sites and Tools

There are 1 software and 3 inspired website used:

Tinkercad: used to make a virtual circuit and simulate it before applying it to check if it is applicable or not and to make a wiring diagram for the circuit of the device.

2. Google : used to find inspirational ideas and ways to apply them and search for solutions for problems faced.

3. Pinterest: used to find inspirational ideas and ways to apply them and search for solutions for problems faced.

4. Autodesk Instructables: used to find inspirational ideas and ways to apply them and search for solutions for problems faced.

5.Arduino IDE: to verify the code and upload it to Arduino

6.Arduino Bluetooth control App to control the components via mobile

Buzzer

Arduino Bluetooth Module

FAN

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?

Inputs

Buttons 1, 2, 3 in Arduino Bluetooth controller App

Action

The fan turns on when pressing button 2.
The buzzer turns on when pressing button 3.
Both turn off when pressing button 1.

Brain

An Arduino UNO board will be used take inputs and generate actions

Identify char incoming data = 0
Identify variables pins 8 & 12 for the buzzer and the fan.
Set the output pins (8 and 12) for Push buttons (OUPUT)
use while loop -->

if incoming data "A" means pressing button 1(Set in the App 1 =A) --> Turn off both (Fan = Low & Buzzer = LOW)

if incoming data "B" means pressing button 2(Set in the App 2=B) --> Turn on Fan & Turn off Buzzer (Fan = High& Buzzer = LOW)

if incoming data "C" means pressing button 3(Set in the App 3=C) --> Turn on Fan & Turn off Buzzer (Fan = Low& Buzzer = High)

Then uploaded the code to the Arduino IDE.
Set Buttons in the Bluetooth control App.

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?

1 Make a diagrammatic sketch for the device showing the outer shape of device

3. Download the Arduino Bluetooth to Mobile Phone and star to pair it with BT Module

4. Write the code and modified it Arduino using Arduino IDE

char incomingData = '0' ;

int Buzzer = 8;

int Fan = 12 ;

void setup() {

pinMode (Buzzer, OUTPUT);

pinMode (Fan, OUTPUT);

Serial.begin(9600);

}

void loop() {

while (Serial.available() == 0);

incomingData = Serial.read();

if (incomingData == 'A') {

digitalWrite(Fan, LOW);

digitalWrite (Buzzer, LOW);

delay (10);

Serial.print ("Off");

}

if (incomingData == 'B') {

digitalWrite(Fan, HIGH);

digitalWrite (Buzzer, LOW);

delay (100);

Serial.print ("Fan on");

}

if (incomingData == 'C') {

digitalWrite(Fan, LOW);

digitalWrite (Buzzer, HIGH);

delay (100);

Serial.print ("Sound on");

}

Serial.println(incomingData);

}

The Electrical circuit simulation on TinkerCad

2. make a wiring diagram for the circuit on tinker CAD by :

add breadboard, Arduino,
Fan motor

Connect one leg of the motor to Pin 12 ).

Connect the other leg of the GND in the breadboard that is connected (to the ground of Arduino).

Connect the Ground to GND (Arduino).

connect the Buzzer

(Positive (buzzer to ) → Pin 8 (Arduino),

negative to GND in the breadboard that connected (to the ground of Arduino).

Bluetooth (BT ) module

VCC (BT ) → 5V (Arduino)

GND (BT ) → GND in the breadboard that is connected (to the ground of Arduino).

TX (BT ) → PIN 0 RX (Arduino)

RX (BT ) → PIN 1 TX (Arduino)

5.verify the code and upload it to Arduino using Arduino IDE

6. wiring the circuit according to the sketch in thinkercad

Showcase the project and check the functionality of the code and components.

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?

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 Bluetooth module didn't appear in the mobile Bluetooth search at first, I checked up the jumpers again and found out that RXD & TXD are connected in the wrong way to the Arduino,

I connected them correctly, and it worked.

I tried to use old Android to control to BT module (this is advice from my instructor Hala).

Final Project

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

using tinkercad portal to design and simulate the final project circuit before i do it physically and i will use the experiences from this week to do the electronic circuit in the final project.

by using BT module may be can do in nice to have to control in servo motor and all building to increase the efficiency of building .

in final project.
