I'm testing three different Arduino (nano, Uno and Mega) each of them having a nRF module. The codes (sketches) are different for each module.
I've connected the arduinos to my single laptop via 3 USB ports.
Problem is, whenever I want to re-upload a sketch and fix a bug, I have to choose board model and port number of that sketch by using the menus. It has become frustrating using mouse each time I need to change something.
How can I set these parameters in code so each sketch knows which port and model it is related to?
