Hallo erst mal an die Gemeinde, bin neu hier.
und hab gleich ein problem auf dem ich nicht ganz so bewandert bin,
hab mir den Tea-Timer nachgebaut 
mit einen arduino pro micro (Leonardo)
damit beginnen meine Probleme der sketch ist für einen arduino pro mini v13
bei meinen läuft das Display und der servo alles in einer endlos-schleife ohne eine Funktion des Knopfes oder des Potis für die zeit einstellung...
könnt ihr mir helfen.
The circuit:
* LCD RS pin to digital pin 14
* LCD Enable pin to digital pin 16
* LCD D4 pin to digital pin 6
* LCD D5 pin to digital pin 5
* LCD D6 pin to digital pin 4
* LCD D7 pin to digital pin 3
* LCD R/W pin to ground
* LCD VSS pin to ground
* LCD VDD pin to 5V
* LCD LEDA pin to digital pin 9
* LCD LEDB pin to ground
* 10K contrast potentiometer:
* ends to 5V and ground
* wiper to LCD VO pin
* selection button to digital pin 2 and ground
* 10K selection potentiometer:
* ends to 5V and ground
* wiper to analog pin A0
* servo motor:
* power wire to 5V
* ground wire to ground
* signal wire to digital pin 7
* buzzer to digital pin 8 and ground
