[sdiy] Divide by 10^6?

[flightofharmony]

Thanks! 
I confess that I don't really know anything in the realm of logic, just
analog. The exact 10^6 is just a ballpark, I just need to slow it down
enough to blink the LED at a visible rate. The 2^20 sounds fine to me! Could
you point me to some datasheets or part numbers please?

Best regards,
