microcontroller parallel programming, how?

[andro]

i want to make a project , but this project dependence on 2 timers
working at the same time. i want enable then at the same time
the first one i named as (main timer) and duration is 30 minutes

it will enable another timer counts for 5 minutes and relay too for and takes a rest for 50 seconds and starting again
5 minutes to enable another relay and again rest and so on to complete 30 minutes.
i want to make 7-segments to display both counters
and uses push buttons to adjust the timing
but i am thinking that,parallel or independent programming
to make two independent sequence at the same time
is not available in programming microcontroller and to achieve that i should use 2 pic microcontrollers
one counts for the main timer and the other counters for sub timer.
what do you think about that ?
can i make parallel programming with one microcontroller or i should
use more microcontroller and the result controlled by one microcontroller??

Dear Andro,

You should use single timer micro-controller with two timers. Such micro-controller are easily available.

If you need a 30 minute timer, a 5 minute timer and a 50 second timer, why not use a single timer that is programmed for 10 seconds, and
use that as a 'tick'? Each time the interrupt kicks in (i.e. every 10 seconds), you can increment counters. If the counter reaches 5 then you know
50 seconds has elapsed; if a counter reaches 30 then 5 minutes has elapsed and so on... This is normal practise. You don't need to use hardware
timer resources for single event timing only, because that would never scale.
