Cheap pump timer

I found an arduino timer model #QF-RD72 splice it into 110 or 220 volt line and your ready to go. You can find them on Amazon foe $5.00 to $12.00 and it work great. I have mind set for 5 min. On and 3 min off. Not sure if this is the right timing but you can adjust the on or off timer for anything between 1 sec to 1 hour endless loop.
