Sketch uses 1319330 bytes (100%) of program storage space. Maximum is 1310720 bytes.

Global variables use 40664 bytes (12%) of dynamic memory, leaving 287016 bytes for local variables. Maximum is 327680 bytes.

Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
