Storage Space Issue

Projects Programming
1

Hey I've been getting this error message on my arduino project and haven't found a way to resolve it any help is appreciated.

Sketch uses 2572 bytes (7%) of program storage space. Maximum is 32256 bytes.
Global variables use 37 bytes (1%) of dynamic memory, leaving 2011 bytes for local variables. Maximum is 2048 bytes.

Here is my code:

Thanks! Sorry I'm new to this so I hadn't the slightest idea.

Hi AlarmGuy89, that message is telling you that you have 32256 bytes of program memory and have only taken up 7% of it with your program. And you only used 1% of the changeable (RAM) memory used for variables. Messages in white font are good. Messages in other colors are errors or warnings.

Arduino messages are a combination of easy to understand, and cryptic. It usually highlights the line that is being compiled when an error is discovered. The actual error is often a line or two away from the highlighted line.

The error message also trys to tell you what's wrong. About half the time this is helpful.

And yeah, the "Resources" menu above has all of this stuff in it.

Thanks I'll be sure to check it out
