Diagram For Optocoupler Combo Board

I made a diagram for the basic layout for the Optocoupler Combo board I whipped up just using some Proto-Board. In the diagram I did not include all of the Optocouplers I'm currently using as it;s likely to change and the format is simple enough to just continue the pattern to add more as needed. I have not added the Digital Compass yet either so I'll be doing another updated diagram later but this gives an idea of how simple it is to connect up some stuff like the Switch Pod button inputs for the Arduino Mega to activate screens in our Knight O.S. Dash Software interface and connect up the LDR and Temperature Sensors. You can see the Optocouplers provide complete isolation between the 12V Switch Pod buttons and the 5V ground pulse needed for the Arduino Triggers.


I updated the diagram to include the connections for the HMC5883L Digital Compass.
