Good evening, my idea is, first verify if there is enough luminosity in the room (or, if the luminosity sensor returns a low number), then i just turn a led ON and a BUZZER to advice that light is missing! then, i show a menu, and depending on the time i hold the button, i turn another LED on or OFF. See the code! Help me, cause there is something wrong
That gives us an idea of what it's supposed to do, but please also tell us what it actually does.
