Arduino: 1.8.5 (Windows 10), Board: "Keyboardio Model 01"

Sketch uses 18888 bytes (65%) of program storage space. Maximum is 28672 bytes.
Global variables use 1932 bytes (75%) of dynamic memory, leaving 628 bytes for local variables. Maximum is 2560 bytes.
Low memory available, stability problems may occur.
