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)

the idea for this week the assignment was

Communicate wirelessly with a Smart Circuit via a Graphical User Interface (GUI) on your phone or PC

inspired by smart home feature when there is a flame or something emergyncy the fan should be on an alarm from buzzer which be controlled by mobile application

This assignment's idea is a Bluetooth control circuit for a small fan that was in the previous week to be controlled by a smartphone.

Tool Chain

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

Bt teminal (mobile application ) use to control the arduino by Bluetooth

Electronic Components:

5V Adaptor for the Arduino, fan and Bluetooth module.
Fan 5volt
Bread Board.
Buzzer
Arduino Uno
Jumper wires.
Bluetooth module HC-05.

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?

1- Circuit main power supply:

I used Arduino 5v output and connected it to
breadboard (+,-) terminals to feed all other components

2- Bluetooth module:

Will communicate with the mobile application (INPUT)
Receive commands from the paired mobile
Transmit these data to Arduino

3- Bluetooth module wiring:

Its VCC is connected to breadboard +
Its GND is connected to breadboard -
Its Tx pin is connected to Arduino Rx pin1
Its Rx pin is connected to Arduino Tx pin0

4- Buzzer (OUTPUT)

Its + terminal is connected to Arduino pin 8 digital OUTPUT
Its GND is connected to breadboard - terminal
fan (OUTPUT)
Its + terminal is connected to Arduino pin 7 digital OUTPUT
Its GND is connected to breadboard - terminal

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?

Variables and Void Setup:

At this stage, I started creating the variables and defining the components connected to the Arduino pins in terms of whether they are input or output

Void Loop:

In this part of the code, I used the While Loop and IF, else Condition Loop to control the fan with a smartphone. When we press button 1, the motor works and the buzzer beeps for half a second and when another button is pressed the motor stops working

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)

While testing the project , the data was not received by Arduino and the code was not working.I found that the Tx of Bluetooth is connected to Arduino TX , and Rx of Bluetooth is connected to Arduino RX. and then i put them in the correct pins and it worked well after
I have to remove the Bluetooth module when you upload the code to the Arduino because it can take wrong signals
