Hi!
can anyone please help to make random number generator?
from 001 to 999, with option to random custom like 354 to 754...
and it it's possible not to show the number right away but to make them random running custom *** seconds like in slots or something,,,


like MXA083 but with time setting and stop option...

It depends what you're after-- this is pretty easy to do in software on a computer, or with a microcontroller. However, it depends how random you want your random numbers to be. Pseudorandom is easy. True hardware random number generation is a bit tricker.

Well, you could take that existing kit and reprogram it-- or you could do it on an Alpha Clock Five (or in any other number of ways) -- but unless there's a full readymade solution to do exactly that, there will be *some* programming required.
