My idea for this week is to build a prototype for a fire alarm system. I plan to use a flame or heat sensor that can detect a fire. The main goal is for the device to respond immediately when it senses danger by activating two types of alerts: an audible alarm using a buzzer, and a clear visual warning with a red light.
The inspiration for this project came from noticing the fire alarms you see in almost every public building. I started thinking about how they work, and I was struck by the idea that such an important, life-saving device could be built from a few simple electronic parts.
What really inspired me was the thought that I could create my own working version using a basic heat sensor to trigger both a sound and a light. The challenge of putting those simple components together to make something so crucial is what motivated me to choose this idea.
Softwares
I used Google to search for ideas and to get visual information that helped me get inspiration and develop the concept.
I used Tinker cad to model and simulate my circuit and to test it before circuit building
For coding and code uploading I used Arduino IDE
Tools & Components
Simulating the circuit generating 2 outputs using 2 output components LED light & buzzer sound , & depending on the sensor of Temperature.
A screen shot of the circuit with :-
INPUT COMPONENTS :
temperature SENSOR to input the temperature value
OUTPUT COMPONENTS
LED to emit red light as alarm
BUZZER as sound source for alarm
Programming phases
After building our circuit & making the wiring and pin out
We start our coding process with the infinity loop block "forever"
Then we use the block of if then else for the condition
After that we use that math blocks and we use the comparison block
After that we use the temperature sensor reading block from the input blocks
After we choose it and detect the bends that it will rain we change the comparison value to 40 degrees Celsius
We start Now to set the output blocks and we sit the values that we need the condition to make
In the other condition of else we use other output blocks with different values
After we fully set our code we head to the Edit mode to change it from blocks to blocks and texts
Now we click on download code to use it on Arduino Ide
or we can copy it by selecting the whole code and paste it on Arduino Ide
Now we open the code on Arduino Ide
and after we check the code
We click on verify and wait wait for it to load
Then we click on upload code and upload the code to our Arduino then we can now run our main Project
Circuit Simulation
A simulation of the temperature sensor circuit
Now with the implementation & circuit building
Now we make our wiring and connect our components to the breadboard and Arduino Uno
We make our input wiring and output wiring and power wiring to the Arduino
After every component is connected to our breadboard from the input components to the output component
And we have already uploaded the code to Arduino we can now run the circuit
Final Output Project
A circuit that contains temperature sensor and a buzzer and a LED that is turned on with the buzzer when Temperature goes above specific value
I had a Problems
It was that when I used the Temperature sensor its polarity was reversed and it generated a huge amount of heat that I thought it was broken or not working well , and it always made circuit work till the Temperature of 300 C
But when I reversed the sensor and tried it worked well with the readings I already wrote
I can now use temperature sensor and good books in my final project properly and I can program using tinkercad and using Arduino I can upload the code and verify the code and make blocks code and play it and upload it using Arduino Uno
The coolest thing in the week is the Mid-week session of Wednesday , it's the most ever coolest thing ever through the week
A thing that I have learned which is so important that you mustn't connect Arduino directly to motors without transistor as they may damage it permanently as they take high value current
For me the coolest thing ever is the mid-week Wednesday session it's I always the Best , it always has funny activities and Manar knows how to always make the session great and funny and the best it's always the besssst I'll really do miss this session I already do now . I do like this session I enjoy it.
In the Hands on session
We made a waving robot that waves with 2 modes , first with ultra sonic mode as automatic mode & with potentiometer as manual mode , it really was a fun and a very funny experiment that I enjoyed, We did great.
We with the 3 wave Robot projects <3
after the end of day and the end of making
our little project
Stages of Project Making & Fabrication
With the team of my peers <3 Yasmine Alaa-eldeen & Mohamed El-alfy <3
We make the 2 hands of the waving robot :) a right hand and a small left hand :)
We make structures for the robot motors to be stabilized on and cardboard outer structure as enclosure
We make our Spooky wiring XD and close the sides of the enclosure and make our friend Bakr :)
And here comes our little cute star
the result of a good team work <3
our little project
We call him "Bakkar" :)
