How to make a Linux powered garden sprinkler system.

Step 7 Other notes...

I learned a lot making this little contraption.

1. bury your line to the garden if it is in a high traffic area or where you will be mowing the grass.

2. don't rely on old printer cables to make a DB 25 connector, it was a pain and it didn't work. spend the 1.25 at radio shack or look them up on digikey.

3. Don't water too much. initially I had the water pressure set too high and was watering most of the yard and the neighbor's yard. ( adjust the pressure with the water spigot.)

4. Make sure your Wall Wart power supply can switch your sprinkler valve. Most say 25 volt AC but I am using a 12 DC Wall wart without any trouble.

5. you could add multiple sprinkler valves and relays to add functionality to your automated system.

6. Any linux remote connection program will let you manually connect and activate your sprinkler. You could operate it from you phone or laptop

Good luck with your own projects.

 You could use some internet service, or rain/temperature sensor, to determine the amount of water that should be sprayed.
