Designing external status indicators

Hello
I’m building a ground station with mechanical gauges and led indicators. I need to extract real time data from mission planner to an arduino.
What kind of software i have to create? What programming language i must use?
Any help?
Thanks

Any luck?

I’m doing a project with my son and we are wanting to use a toggle switch to arm the quad/plane w/ an Arduino.
