Its 60ns on my signal and 1ms on the loop. Should work just fine.

In my language, that's tens of nanos.

If it all works please share your code how you got it to work.

Thanks,

In theory the jitter could be sub nanosecond, its the granularity that's 66ns.

The LEDs and a Camera are controlled by the sync signal of the Arduino. I use the array to measure how long the Camera needs from the trigger signal to the first picture recorded on different frame-rates. I will post the code once its done... its a very slow progressing project since every time I need something, i need to google and play around till it works :)    ..but its a good way to learn this stuff.
