Arduino nano compiling hatası

[gparadiso]

Merhabalar ben bu kodu dün nanoya atıp çalıştırdım fakat bugün aynı kodu derlemek isteyince
text section exceeds available space in boardSketch uses 30918 bytes (100%) of program storage space. Maximum is 30720 bytes.

Global variables use 617 bytes (30%) of dynamic memory, leaving 1431 bytes for local variables. Maximum is 2048 bytes.
Sketch too big; see https://support.arduino.cc/hc/en-us/articles/360013825179 for tips on reducing it.
Error compiling for board Arduino Nano.
böyle bir hata alıyorum nasıl düzeltebilirim?
