Sketch size is 109%

[mmanchev]

Hi, I want to implement this project. I've gone trough the sketch and all libraries, and it compiles successfully, but it's oversized. My board setup is Arduino Leonardo, which I found is the analog of the Pro Micro. This is the error message -
`arduino_build_334303/JBC-Soldering-Controller.ino.elf
Sketch uses 31454 bytes (109%) of program storage space. Maximum is 28672 bytes.

Global variables use 808 bytes (31%) of dynamic memory, leaving 1752 bytes for local variables. Maximum is 2560 bytes.
Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Error compiling for board Arduino Leonardo.`
