Feeling confuse with choosing arduino board

In my project i have 3 cycles of operation and for each cycle will start after pressing push button and each cycle consists of 3 relays to operate at different intervals of time.

My question is can i operate 2 cycles simultaneously or i need to operate with individual boards.

Plz help me out.

That should easily be possible with any Arduino board. The Uno is the best beginners board because most programs and add-ons work with it.

For the business of simultaneous cycles have a look at the demo Several Things at a Time
