Thanks for your reply.
Power delivered by Arduino may not be enough for cleaning time (60 seconds with 5V), because I measured and sometimes not reached 5V only getting ~4.7V. Relatively to 1.5V, the Arduino provide this power correctly, i've tested for this case.
But if the Arduino does not provide 5V for cleaning time, how can I improve it with another alternative circuit that respects the times (60 seconds - 5V ; 90 seconds - 1.5V)?
