Portable Fan with SUPER EASY SPEED CONTROL! (Arduino)

- In this video we create a portable handheld fan where you can very easily control the speed efficiently. It is an Arduino project and the speed of the DC motor is controlled using multiple ways, a potentiometer and a PWM signal from a micro-controller coupled with a MOSFET. It's a great Arduino project to do, to learn how to control the speed of a DC motor (fan). I show three ways you can control the speed of a DC motor (fan) in this Arduino project. Using a potentiometer, motor driver, and using PWM signal from an Arduino micro-controller, such as the Attiny85.
The main learning point of this Arduino project is to learn the different ways to control the speed of a DC motor. I first go through showing how to do it using a potentiometer, however, this is not efficient and should not be used as some of the voltage/current is lost into the potentiometer. I then suggest a motor driver to control the speed of a DC motor, however, for this project, it will be an overkill and too big. The final way I show is to use a PWM signal from a micro-controller, the Attiyn85, coupled with a MOSFET to control the speed of the DC motor, which ultimately is the speed of the portable fan. I also briefly explain what a PWM is. Using a PWM signal to control the speed of the DC motor is very effective and efficient.
I show the full schematic of the Arduino project, as well as the breadboard wiring, and I also show how to make a stripboard version to make the project super small and have a small footprint.
Using a 3D printer, three parts are 3D printed, which then makes up the portable fan. To design all the 3D models I used Fusion 360, and printed them using the Creality CR6 SE 3D printer.

When I've watched couple of your videos, i looked at the amount of subscribers, it said 700, i thought it says 700k, but it's only 700, you really deserve much more people to watch Your videos!😄
I'm impressed by your videos flow and content of the information. Great stuff 👍
Thank you, I appreciate that!
I really liked how you are giving little advices along the way (like on 7:42) so that we can learn on your mistakes, that's the best thing!
By the way, i just thought, what if we just used cheap adjustable voltage step up or step down converter for lithium batteries to control the voltage? It's like 0.5 to 1 dollar
No worries! I am glad it helps. Yes that could work.
Very nice!
Great work!! Keep going brother...Love your videos. At 5:10 the cell symbol is reversed.
Thank you very much! I really appreciate it! Yes that is right, well spotted! This is exactly the type of community I want to build!
@@ProjectsWithRed Keep going brother. I am gonna be your regular supporter.. love from Nepal
@@gauravbhattarai75 Thanks a lot! I am glad to hear that.
Everything is great in this project, the only thing i would change is using tp4056 with type c port instead of micro usb, it's 2020s already, we should all stop using micro usb 😅
You are not wrong ;)
Reverse diode or it blows up.
