Week #6 - 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 is to make ventilation fan controlled by temperature sensor, so when the Temp. is high than 25 c, the fan run automatically to reduce the heating degree.
This idea would help to keep on suitable work area without Air conditioning which save costs and save environment.
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
I used different Thing as below:-
A- Tinkercad to do simulation for the blender components.
B- Bread board, wires, 5V fan, arduino UNO board, LM35 Temp. sensor.
C- Avometer.
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?
Tinkercad blocks show if read temp. sensor is bigger than or equal 25 set pin 6 to high and if no set pin 6 to Low.
Choose If from control as logic condition.
Choose bigger and equal than from Math.
Choose set pin from output.
C hoose reade teamp. sensor from Input.
The process of simulating come as below:-
Open tinkercad website.
Log in the account.
Choose create circuits.
Add Arduino UNO board ,breadboard,and DC motor and Temp. Sensor to the work space.
Assemble all components together as the picture attached.
create the code as blocks.
Run the simulation to stand on the result.

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?
The implementation process come as STEPS:-
first prepare the components on the work area as below:
Avometer to measure the volt and current in the circuit.
LM35 Temp. sensor.
5V fan.
Arduino uno board.
wire to connect all components together in the breadboard.
USB to Arduino connector to get the power
Second create the circle :
connect positive and ground from Arduino board to bread board.
put the LM35 on the bread board.
connect ML35 voc to the positive on the board and cround to ground on the board.
connect output LM35 to the Analog input on the board.
connect the fan t the positive and ground.
Upload the code to the Arduino board.
Note: some DC 5v Fans need relay to run with the Arduino as out-source of power because the Arduino board current is low to run it.
int val;
void setup() {
// put your setup code here, to run once:
pinMode(A1, INPUT);
pinMode(6, OUTPUT);
Serial.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
val = analogRead(A1);
float mv = (val / 1024.0) * 5000;
float cel = (mv / 10);
Serial.print("Temp = ");
Serial.print(cel);
Serial.print("c");
Serial.println();
if (cel > 25) {
digitalWrite(6, HIGH);
} else {
digitalWrite(6, LOW);
}
delay(100);
}
6-v1.mp4Overcoming 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)
The challenge was to change the Temp. sensor LM35 code than in tinkercar because in Tinkercad is different type of sensor.
So i write the code as i saw in lecture video by identify the value and then divide value on 1024 as analog read data multiply 5000 then divided by 10 to return to Celecios degrees
as Below code:-
val = analogRead(A1);
float mv = (val / 1024.0) * 5000;
float cel = (mv / 10);
Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
This assignment really nice to my final project because i learned how to get temp. degrees displayed and control the Tem. sensor with Fan which i can later change fan to buzzer and led as alerts.
