hi! (hi)
i'm going ahead, I'm not a specialist, just a hobby. I'd have a question, maybe it would be helpful. I have a project that I want to display on a color OLED display which of the two devices is turned on "on -Off". I would ask for help, arduino mini pro for the subject and full color OLED 240x240 pixels, 1.3 "thanks to Bady : Smiley-összekeverik:
What have you tried so far ?
Start with the example code that comes with the library you are using for your OLED. Get it to work on your setup, then begin to modify it to do what you want (display On/Off).
If you get stuck, read the sticky posts at the top of this forum about how best to post your code and where you got stuck and people will try to help you.
