Hi, I am new to the forum and not super versed in circuit design, but excited to learn more here.
I have been trying to design an optocoupler circuit to allow me to "listen" in on my 24v Thermostat calls to my Taco ZVC405-4 zone valve which controls my radiant hydronic heating in my home. I would like to be able to watch for the calls via an Arduino microcontroller.
I have done a number of Arduino (low voltage) projects, but am trying to make sure I go about tying into a line voltage...
