This week, we have to build a simple electronic device that performs two actions. Because I need a Lampshade in my home, and also a mini portable fan for the next summer; I decided to design one device for these 2 functions. I searched for many designs on Google, but finally, I worked on it with my special perspective on the design and I went straight to the work...
Components
The medium size to be suitable for the enclosure.
For the arduino and because the fan works only with 5v power source not 9v or more
When the user turns on the switch, the fan will open
When the user turns on the switch, the bulb will open in yellow color
To turn on and off the whole project.
To connect the components all together.
Materials
Software
To design the circuit and test it on it.
Input components: on/off switch.
Output components: bulb, fan.
Parallel circuits are often used instead of series circuits because they offer several advantages. Firstly, in a parallel circuit, if one component fails, the other components can still function normally. In a series circuit, if one component fails, the entire circuit will stop working.
Secondly, in a parallel circuit, the voltage across each component is the same, while the current through each component can vary. This means that each component can be designed to operate at its optimal voltage, which can improve the overall efficiency of the circuit.
Thirdly, adding more components in parallel does not increase the overall resistance of the circuit, as it does in a series circuit. This means that adding more components in parallel will not cause a decrease in current or voltage, which can be important in this application.
Inserting breadboard
Inserting the power supply and adjust it on 5V because the fan works only with 5v power source not 9v or more
Inserting dc motor insted of the 5V fan
Inserting bulb
Inserting pushbutton insted of on/off switch
Connect the power source and connect the motor and bulb in parallel and the pushbutton in series
Starting simulation and all is done :)
Firstly, I connected the components on the breadboard like the circuit design in tinkercad
Then, I tested the circuit and all the components and functions worked
Closer view to the circuit while it was working
After that, I designed and created the cardboard with a space for the fan, and arabesque shapes and ports for the switch and the cable of the adabter
I turned on the circuit and it worked well :)
Side view for the device to see the lights. The device allow the user to put his mobile on it also
A view for the lampshades in the dark to see its light effect at the night <3
When I tested the circuit at the beginning, it didn't work because I used a 9V adapter where I was using a 9v power supply in Tinkercad, and the circuit worked without any problem or alarming me to change it to a 5v power source.
So, I changed the voltage for the power supply to 5V, because the fan works with 5v, not 9v, and used the 5V adapter and the circuit worked perfectly.
Right now, I feel that I'm on the way to understand my project requirements, specially after practicing h-bridge which inspire me to do a lot of devices by it in the future :)
I loved more the idea of DIY (Do It Yourself) after this experience and I hope to do many ideas for my home and my family :)
It was the most wonderful moment in maker diploma when we created the RC car using h-bridge. I really loved this project and I loved more the competetion that we experienced, specially after wining of my team :)
