104 nano seconds

Using Arduino Programming Questions
1

am having problems my arduino uno, writing timing of 104 nano seconds, please help
Thanks

You have milliseconds and microseconds.

The arduino only has a 16Mhz crystal which is not nearly fast enough to do anything in nanoseconds.

What do you want to do in 104 nanoseconds?

Better still tell us what the real problem is, then we can judge if 104ns is relevant
in the first place, and if so what precision is needed.

Thanks, I was trying to do video conversion for my small led screen

In that case, forget it.

FYI 104ns is less than two clock cycles.

Then you need a video conversion chip perhaps?

Can't I get another arduino board that can help?
And I thought on the uno with 16mhz, 62ns would be its max period? So my 104 ns is not even up to

2 cycles of 62.5 ns (16MHz) is 125ns, which I think you'll agree is greater than 104ns.
Even a Due at 84MHz is going to struggle to do much sensible in that kind of timescale.
