Why the ground wire on the toggle switch.That will short Vin to ground when the switch is in the off position and the left relay is active.Remove that ground wire. You don't need it.Leo..
wall wart to arduino jack should be fine.12V to solenoid also fine PROVIDED that the connections are correct.These are missing from your fritzing diagram.I have converted your fritzing diagram to a circuit diagram which shows other problems but am unable to post.Describing in words is probably pointless.A photo of your actual setup could probably be better even if it is not a good pic.Your fritzing diagram lacks detail as well in that its difficult to read the legend.That may be a drawback of fritzing though.
What is the purpose of the toggle switch. Ability to bypass the Arduino?So the toggle has a LED.Do you have a link to the switch.Leo..
Everything is in my diagram... both water valves, switch, relay and i don't have a 12v picture of my PSU but I
No its not.Components are there but the way they are connected are not.The power connection circuit is very important even if you get the signal pins connected correctly.
Right. Did not know you had a switch with a LED.Toggle is the wrong word for this switch (blame the website), hence the confusion.It's a SPST switch with LED ground.Seems to be wired correctly.Leo..
I agree, its built in.
