Low Memory Alert After Compiling...

Dear All,

How to reduce the memory usage when the seeing the message below after compiling? Which part in the sketch should we look into it?

Sketch uses 26,260 bytes (81%) of program storage space. Maximum is 32,256 bytes.
Global variables use 1,609 bytes (78%) of dynamic memory, leaving 439 bytes for local variables. Maximum is 2,048 bytes.
Low memory available, stability problems may occur.

Thanks.

Regards,
Kimble Gray

On all your Serial.print ( 'Text here' ) ; change them to Serial.print ( F( "Text here" ) ) ;
The F( ) macro stores the fixed text in Flash memory instead of copying it to the stack. Easiest way to free up memory.
