meaning of results after click "verify"

HI! this my Result program after i click the "verify"

Sketch uses 1,030 bytes (3%) of program storage space. Maximum is 32,256 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes.

It's just an information, nothing to worry about. That means code compiled without warning and errors. It should be working :)

thank you for this information :slight_smile:

This message is telling you how much of the memory on your Arduino board is used by your program. There are two different types of memory. This is important information because the memory on the Arduino boards is very limited so when you write more complex programs you need to be careful to write efficient code. It can be useful to see what the effect of a given change is. So you might "verify" your sketch before an after and then compare the reported memory usage.
