hi thanks for the answer and sorry for the bad description.
i’m doing a radar project, with the arduino i send distance to processing and i want to show it there. because background(0) i want to leave it that way, that’s just the background color, right?
i just tried to make an example:
fill(0, 139, 0, 139);
that’s how it works. but the measured distance always changes or stays away.
I’ll take a picture later to pinpoint the problem.
