Welcome to CNC
Hi Vina, great project have just finished it but have a problem the relay activates when I touch the wires with my fingers but not in water. Will changing the resistor on the main terminal fix this, if you could help I would really appreciate it again a great project. I am using it to keep a fish pond full with a 12v solenoid valve.
This a great instructable with lots of ideas, if you could please post a schematic of the wiring I would be gratefull.
