LCD WITH I2C

Projects Programming

Most of the messages are warnings.

But this:

LiquidCrystal_I2C lcd(I2C_ADDR, 2, 1, 0, 4, 5, 6, 7, 3, NEGATIVE);

probably does not match the library you are using. Maybe try using false instead of NEGATIVE or look for an example in the library folder which you can adapt.

and this:

 while (sequence[i] != NULL)

do you mean:

 while (sequence[i] != '\0')
