In the beginning, the idea of the project resulted from a problem, which is that my laptop overheated when playing games and some programs, and it was a problem I wanted to solve, then I joined a maker diploma and had the opportunity to implement a smart laptop cooler using sensors and smart components. I got excited about this idea to fulfill my need and solve a problem. And simply, it will work to cool the laptop only when it gets hot and not all the time with the addition of some aesthetic lights.

• And this is a similar design

Software:

Materials:

The main power source of the project is 12V adapter, but at the beginning I used two adapter 12V and 9V to power the LED strip and the Arduino, Then after using voltage regulator I could use only 12V

• Firstly, I detected my process steps and what are the input or output. Which the first function was run the fans by the DHT11 sensor, so I installed the library of the DHT11 and define the reading pin which it A0, then in void setup start serial print to show me the reading of the sensor and make sure that it works or not and then define the A0 pin as an input and Fan pin as an output.

Then in void loop I stored the values of the temperature and humidity and print them and then start IF condition which if the DHT sensor sense Temp more than 25 of Humid more than 60, the Fan pin will run and therefor the 3 fans will work.

• Secondly, the second function was run the RGB LED strip by the sensing of IR sensor, so I defined the reading pins of the RGB which they REDPIN, GREENPIN and BLUEPIN, and then define them in the void setup as an outputs and the IR as an input.

Then in void loop start the IF condition which if the IR sensor sense the laptop, the RGB will feeding and make deferent colors and if the laptop isn't on the cooler the RGB will not work

I was asked instructor Amany about her feedback for my design and she told me to use a 3D printed hinges instead to the metal, Then I did and it was really better than the metal hinges

Also Mohamed Adel help me to make the wiring of the relay modules with the fans and he suggest to me to use only one relay with the three fans instead to 3 relays and in works

And instructor Ibrahim helped me to use only one 12V adaptor instead to two adaptors 12 and 9V by using the voltage regulator and it is works

I had a challenge with the use of the motor driver because I do not know how to use it with the RGB LED strip. Then I searched for how to wire it and how to wire it with the RGB LED strip, and I asked instructor Ibrahim, and in the end he worked

Also before the fabrication I discovered that the metal hinged is bigger than the legs of the cooler, then Instructor Amany give me a solution which print a smaller hinge so I did and it worked.
