For a school project I have to make different colours come up on one of my lights for my arduino uno I’m using c+ code and I don’t know how to do it
What have you been taught about the Arduino ?
and are we supposed to guess what this is?
one of my lights
C+ code doesn’t exist so that’s not a good start. There are lots of different types of “lights” but I expect you have something specific. Details might help. Have you tried to make your “lights” do anything yet? If so post some code that you have tried.
Never mind a figured it out
