500 us shouldn´t let you see much of it, do you remember how we humans can hardly see 1/60 seconds events (light bulb), well 500 us is much less than that, maybe 500 ms is easier to watch.

Try Pause 500 instead uf pauseus 500.

Of course you could also avoid turning the leds of as the previous post said and then the leds would only change when data is recieved.
