Arduino POV

Persistence of Vision or [POV] is an optical illusion whereby multiple discrete images blend into a single image in the human mind. I.e. when you look at a working fan, you'll see its blades forming a transparent circle! But, Why?!

The eye hold information for an instant longer than it's there and the brain merges those images together in one scene. This is because that the images we see take about tenth of a second to be registered in our brains, so when the blades move in a time less than tenth of a second, the brain combines the images of the different positions of the blades together and we start to see that circle.

 MATERIALS

The first thing that you are going to need to do is gather all of your materials. You will need:

1.  7 LEDs ( any color )
2.  7 Resistors (220 ohm)
3.  Arduino UNO
4. Breadboard
5. 7 Jumpers
6. 10 Staples

ASSEMBLY

1.) First, put the 7 resistors in the breadboard

2.) Then, put the 7 LEDs

3) Next, put the s10 staples in according to how they are in the picture above

4.) After that, insert the jumpers in the breadboard and the arduino

5.) Finally, just plug it to a power source (you can hook it up to your computer or to a 9v battery)

If you want to, you could also zip tie the arduino to the breadboard so that they stay together.
THE CODE

In order to display your message, you will need to modify it. Just open the arduino sketch and change the message length and message itself.

Once completed, just wave it infront of a slow shutter speed camera to see it
