LAURRENCE2021 Posted September 16, 2021 Share Posted September 16, 2021 Greetings I am looking at running the whole caution panel on an Arduino mega to make the coding easer from DCS Bios. With the 40mA limit per pin and the total Loading of the Arduino chip at 200mA I was thinking of using a bank of NPN transistors, using this method it's only drawing 400 micro amps according to the electronics simulator, enough to light the lot Thoughts and comments most welcome Electronics Simulator is TinkerCad from Autodesk Its Freeeeeeeeeeeee Link to comment Share on other sites More sharing options...
Looney Posted September 23, 2021 Share Posted September 23, 2021 You might want to look into a matrix style set-up for your LEDs in order to make sure one mega can run all the warning and caution lights. https://www.arduino.cc/en/Tutorial/BuiltInExamples/RowColumnScanning as an example. It frees up pins and still allows for lighting or flashing each individual LED.

LAURRENCE2021 Posted September 24, 2021 Author Share Posted September 24, 2021 Hi Looney I did look at this option but going to be a nightmare to program with dcs bios, also cost a few quid for all the matrix units needed I will go with mine at the movement and post an update when complete and working cheers Link to comment Share on other sites More sharing options...
