Serial Monitor don't reponses when I have this code.

hi everyone.i new here , not @ english sorry english.
i use arduino uno r3.i have problem code attach below(this summarize 1 , doesn't work too). don't know why when upload , open serial monitor, type , enter number. doesn't response,but when delete red code(one of them or both), works well.

code: [select]

#include <lcd.h>
#include <liquidcrystal_i2c.h>
[color=red]#include <wire.h>[/color]

float deg_per_sec,rpm;

thank you help.

you've got 1600 bytes of ram wasted in tables.
you have 2048 bytes of ram in total.
if they're constant, they'd better kept in flash.
