This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
this code show to me < when i verify my code
what can i do ?!
There is multiple library named LiquidCrystal.h.
Remove all.
Use proper LCD header file where LiquidCrystal_I2C::begin(int, int) funtion is declared or defined.
