Do Pins Arent Working

Try to make this as simple as possible.

None of my DO pins are working. They all stay on (12vdc) They never shut off. I used the digital port in ARC and assigned the port and many others to test. None of them shut off. Im measuring between red and black by the way. Thanks Chris

The VCC (red) should always be on and the same as the input voltage (12v if you are using a 12v battery). The Signal (white) is the line that goes on and off when you turn the port high and low. It will be regulated 3.3 volts.
