Thank you. Good to know that I'm starting to think in the right lines.
Out of interest - and this is purely a hypothetical question - how would I
have two timers, both firing at 2 second inteveals but separeted by a
second?
I realise that timers aren't _very_ precise, hence the question may be
nonsense. I'm just curious.
