pov display with arduino

Dabu WhiteHacker · Jul 3, 2018

i was making pov display with 10 leds using arduino
but it seems it is not working as it should
here is the code
https://hastebin.com/etovafuvab.cpp
i would appreciate an kind of help

Code:

My browser says the site can't provide a secure connection. Post your code on this site, using code tags so any formatting is preserved.

Also kindly explain what you want the LEDs to do, and what they're doing.

POV has many definitions. I had to google to find out what POV meant in your context.
Point Of View is the most common usage.

MrChips · Jul 3, 2018

"Porn On Video" or "Post Operative Vomiting" seem more applicable in this case?
Or is it "Peak Operating Voltage" since this is the most electrical?

dl324 · Jul 3, 2018

When used with display, I think Persistence Of Vision is more applicable; but I still had to google it.

OBW0549 · Jul 3, 2018

I refuse to play guessing games, and am opting for "Prostitutes On Video."

The OP could probably help us help him by describing exactly what his circuit is supposed to do, and what it is doing instead of doing what it is supposed to be doing. "Not working as it should" is not a very useful description.

Hello,

I think Persistence Of Vision Too.
Here is an article from Make about the subject using an arduino:

Code run through 'indent' and a some manual formatting on the character definitions:
