This is my first post here and I hope I explain this correctly.
I am seeking to make a solenoid valve switch on and then off (for oil) after a given interval. It is AC powered, it will be activated by a light sensing circuit. I have been advised to look at relay circuits and driver circuits.
I was told to use LDRs and LEDs. Am I in the right direction?
The plan is once the LDR senses the light from the LED the solenoid valve will be activated. Im not really sure about the outputs yet because I'm still trying to figure it out.
