Introduction: How to Make a Fan POV Display

About: Awesome Electronics Tutorials, Projects and How To´s

In this project I will show you how I transformed an ordinary old Fan into a LED POV Display which can present you light patterns, words or even the time. Let's get started!

Step 1: Watch the Video!

The video gives you all the basic information you need to build this project. In the next steps though you will find all the files I created which you can use to create a similar POV Display.

Step 2: Order Your Parts!

Here you can find a parts list with example sellers for your convenience.

Step 3: Create the Wooden Stick!

Feel free to download and use my design.svg file to create a similar wooden stick that I used in the video. Make sure to open the .svg file with Google chrome and print it out without any margins.

Step 4: Build the Circuit!

Use the here presented schematic and reference pictures to create the circuit.

Step 5: Upload the Code!

When uploading one of the three Arduino sketches to an Arduino Pro Mini it is necessary to use an FTDI breakout. After a successful upload the project is pretty much complete.

Step 6: Success!

You did it! You just created your own POV Display!

I made it , but there are not all the letters in your code , how do i code them ?

Thanks for creating a very clear instructable. I didn't know about the hall sensor, and I used it for another spinning electronics project.

no hall effect sensor. i have reed switch.how to connect it.and how to programe it

Not with a LiPo cell as a power source.

Will button cell work?

i used one and it worked just fine !

Can i use another type of hall effect sensor like SS49E or A3144 hall effect sensor instead ?

i dont have hall effect sensor

Hey great scott. Regarding the battery management, do you have a recommended procedure/charger to recharge the battery?

Hey great scott.i just wabt to ask that can i use a 9volt battery instead of the lipo battery???

If the arduino mini can support it, and keep in mind that it will ad a lot of weight to the wooden stick

Can you code/programme it to act as a clock? Man it would be so cool!!

1 reply

yes, but it can take hours,and you have to adjust the time every time you turn the arduino on

I'd love to see this on a ceiling fan with RGB LEDs in time to music.

That was a great project!! Nice work
Can you please tell me how can I display images or animations through the LEDs??

Hey.i made a pov display just like u showed in the video but it isnt working.when i turns the switch on it just flashes a red led in the arduino mini.plzzz help me i am stuck
