 #Arduino set-up:
-* Open the Arduino IDE.
-* Connect Arduino (I used USB).
-* Choose correct board and serial port in Arduino IDE.
-* Upload code to Arduino using the IDE.
-* Open serial console (Ctrl+Shift+M).
-* The board waits 4 seconds after Arduino reset (end of upload).
-* Then it promps for I²C address.
-* If you miss this prompt, just enter the address.
-* If you don't know the address, enter the character 'P'.

 #Getting started:
 If you opened the serial console soon enough, you'll be prompted for an I²C address or a 'P'. If you did not open the serial console within four seconds after the Arduino reset, you will not see the prompt, but the Arduino will still patiently wait for your input.

 __The Arduino wire library works with 7-bit I²C adresses.__
 
 The Arduino Serial library can easily parse decimal values, not hex codes. Therefore the default T24C02A address 0xA0 is rendered thus:
-* Right-shift one bit to get 7-bit address: 0xA0 >> 1 → 0x50
-* Convert to decimal: 0x50 → 5×16 + 0 = 80
