Firstly, many thanks to dhudach for giving me a good grounding in Arduino code and parsing data.
I recently got these indicators working. The undercarriage indicator is typical of Lightning, Gnat, Hunter etc..
The JPT indicator, I'm not sure what aircraft it's from but isn't a million miles off Lightning.

I'll be demonstrating this simulator project at Newark Air Museum's CockpitFest event this weekend. Hope to add a little more functionality by then too.
Cheers, Scott
