/*
I am using the LiquidCrystal_I2C.h lib which points to
https://www.arduino.cc/reference/en/libraries/liquidcrystal_i2c_hangul/

To use Servos at the same time is a better library as it has no conflict like 
it is the case of the one from Frank de Brabander
The library it is authored by 
Junwha Hong, Dohun Kim, HyungHo Kim
/* Note:

i2c, unlike the Serial Port Protocol allowd for 
multiple clock speeds to be used so, we have an extra wire
to set the clock. Thus we need two GPIOs:
one for data (SDA) and another for the clock (SCL)
in Arduino UNO the GPIOs are
A4 for SDA
A5 for SCL
so we need to connect these to the i2c controller
behind the LCD display
