Note: my electronics experience is moderate, I can read schematics and can easily develop circuits... but I am a bit weak in designing them.
I would like to build a panel of LED indicators in my RV that monitors the position of the external compartment doors and other closable or lockable devices. I could use magnetic switches or such and use the 12v power that is constantly available to me. I would like the position of each switch to be indicated as open or closed by either green/red LEDs or by dual color LEDs. If you could help with a simple schematic with suggested values for the resistors and such, I would be very greatful. thanks.
