So some of my friends at the local airport have a sim that has been sitting and they want to move to a new software platform (and it does not work at the moment), the switches such as the ignition, mag, master, flap, lights etc. are connected to an Arduino board already. What I need to do is figure out what switch goes to which input on the Arduino, no one ever documented it. I could get out the DMM and do a pinout which would be very slow and time consuming. Does anyone know if there is some simple/basic software that I could simple load onto a laptop, connect to the Arduino via USB, and as i exercise the switches it will show which input is being used?
I am new to this Arduino "stuff" so any help would be greatly appreciated!
Thanks in Advance
