Creating a Count up timer that will display HH:MM:SS on an LCD

Hi, I am using an FTDI USB to TTL Converter to program an Arduino Pro Mini with an UpTime Counter code for a 1602 BLUE LCD 16x2 HD44780 with IIC I2C Serial Interface Adapter Module Display. #include <Wire.h> //#include <WireIMXRT.h> //#include <WireKinetis.h> #include <hd44780.h> #include <hd44780ioClass/hd44780_I2Cexp.h> #define SDA A4//DIO #define SCL A5//CLK //hd44780_I2Cexp display(SCL,SDA);// instead of TM1637Display /*-----( Declare Constants )-----*/ /*-----( Declare objects )-----*/ /
