So the thing is, according to the relay specs, it states that it needs to switch High to energize the relays. The buttons I have need to be turned on with ground, or Low for the RGB halo to light. They share COM (+).
I was hoping to energize a relay module with low so I could use the controller output to light up the buttons when relay was being energized Then when the circuit is off I need a ground or low triggered to a different LED on the button.
My relays unfortunately need to switch 12 volt positive or high from the COM to N/O. So unfortunately I can't use the NC to energize one of the LEDs when the circuit is not active because it needs to go to ground or low to light it. Uggg
Unless I'm still missing something here.
To specify on the buttons again they have 3 LED's. RGB. They all share common positive and are individually lit up when ground is applied to one of 3 appropriate ground terminals. I want the red LED to light up when the circuit is energized and then the green LED to light up when it is not energized, but from my understanding they need ground triggers. DPDT was clutch to achieve this, but I couldn't find any DPDT relay modules, 10 amp capacity or more, that could be controlled from the board directly without another product in between...
So this is why using multiple outputs on the mega seems to fit???
