Yes. That completes the circuit with the bread board.
At this point I am confusing myself.
I have a power supply connected to the BREAD BOARD.
I then run a ground (-) and positive from the BREAD BOARD to each of the RELAY MODULES.
I connect the ground to the GND and the positive to the JD_VSS which are both located at the corner of the RELAY MODULE.
Do I still need to connect the GND next to IN1 on the RELAY MODULE to the GND (-) on the BREAD BOARD?
Is there a way to test this prior to installing the wires to the irrigation valves?
To further confuse myself do I install the RELAY BOARD plugin? If so do I set the RELAY CHANNELS to equal the number of RELAY BOARDS. For example do I set it to 2 for (2) RELAY BOARDS with 16 total modules?
Regarding the 10k Ohm resistor do I insert it BELOW the PURPLE wire and any jumpers going to that ROW or does it even matter?
Thanks Again.
