This sketch works properly, as it does everything I expected, but I am unhappy with the performance. The buttons are too quick to respond. I think I need some kind of "debouncing" to make the buttons less responsive.
Now for the unexpected part : Button 3 will change states on its on from time to time. I dont even have a guess about that one.
So, any help would be appreciated.
This Sketch is running on a MEGA 2560 with a seeedstudio 2.8 tft v2 display
