So when it comes to using the right integer numbers inside a sketch for an Arduino Nano, when it comes to addressing the right pins in the code, there seems to be a variety of information out there and none of it is consistent.
When I’m defining variables in my sketch (for example):
#define RESET 3
#define pin11 14
#define pin12 .15
How the heck do I know for sure which numbers are literally assigned to each pin on the Nano? I’ve been having a hell of a time getting a TFT display to work because I just have no way of knowing, which pins I’m actually addressing in the code.
Any enlightenment on this would be much appreciated.
