Best way to to set up 4x4 keypad for project

[animal12]

Trying to ad text to a sketch

Am I doing something wrong with my library & code ? I went through all my library's that said they were installed & got rid of everyone that had Adafruit liquid Crystal display . My code still shows `#include <Adafruit_LiquidCrystal.h> Adafruit_LiquidCrystal lcd(0x27,20,4);` Shouldn't those disapear when I remove the library ? So far I nave tried Cheap LCD, I2C_LCD , & it won't let me compile cause I keep getting this error code /Users/mikeallen/Documents/Arduino/Lathe_Control_UNO/Lathe_C…

Post # 50 . I quoted the text in 6 in this current thread" Best way to set up 4x4 keypad for project "
thread .
