I want to make a timer that will trip a relay to turn on a pump every 10 minutes. Thats easy, what I can't figure out is how to make it turn the pump on at 10 minutes, then run the pump for 1 minute, and then start over. This is a project for my fishing boat, I need to conserve my battery, but I need to keep my fish alive also. The way it is setup now it will run untill I turn it off, I need it to run for 1 minute every 10 minutes untill I turn it off. Any help would be appreciated. I'm poor and would like to build it myself, I have found products that cost 75-100 dollars that will work but I'm trying to not spend much money on it. Thank you!
I think this will work but its expensive and "overkill"
