Hi, I have a sketch that works now with lcd menu and momentary on switches(saves to eeprom)but I want to add PC control to it. My problem is I need to send up to around 40 different variables of mixed types to arduino. Not only do I need 40 or so different values sent but there is 4 different sets of 40 or so variables....Using mega 2560 so there's plenty of room for sketch.
I've been trying to think of an elegant solution for this but coming up short. Any ideas?
