Hi All,
I want a timer circuit diagram which will turn on a water motor everyday morning, and motor should work for 10 or 15 min and again it should turn off.

Thanks
Samba Damerla

Hi,

a 24 hour delay requires more than just one timer circuit.

You could go the way to use a light dependent circuit which activates a timer for the 15 minutes.

Use the CMOS version of the NE555 (TLC555) for such a long delay.

there are some timers with mechanical set and reset for on and off used in ligthing control panels, it requires a voltage input and makes a 360 rotation in a day. on the dial short of dip selection is there to select on and off intervals.
