            35. // This sketch do NOT work with an ATtinyX4 and ATtinyX5 since they do not have a built-in harware UART (no Arduino Serial object).

            37. // S=P with:

            38. // S=A for Servo1 and S=B for Servo2

            39. // P=Position number x 20° (Possible positions are from 0 to 9 which correspond to from 0° to 180°)

            40. // Ex:

            41. // A=7 sets Servo1 at 7 x 20 =140°

            42. // B=3 sets Servo2 at 3 x 20 =60°
