I have a wiring question.
I made a bit of a goof, when I purchased some great looking LEDs for my gear indicators. The look a lot like the real ones. The problem is that after I bought them, I realized they are 12vdc LEDs.
My question is in activating them. I had planed on using the OpenCockpits IO card to send the 5 vdc to the LEDs by the use of SIOC code. Do I need to use a relay that will be activated by the 5 vdc signal to get 12vdc to the LEDs? If so, how do I turn them off when the gear are up in the wells?
