                Modifications :-
                
            - The LED pins connected to the ATtiny44 were modified,
            - Uncommented the " #define COMMON_ANODE " in my case (as my RGB LED has a common anode)
            - adding various different colors through their codes. */

Red, Green and Blue LED on the microcontroller*/
