Hi
my name is Tarek

i am new to arduino and i have a problem
first of all here is the code

String value = "RED";

int pushButton = 2;


void setup() {
  Serial.begin(9600);
   pinMode(pushButton, INPUT);
}

void loop() 
  int buttonState = digitalRead(pushButton);
if (buttonState == HIGH){
  if (value == "RED"){
    value = "GREEN";
    }else if (value == "GREEN"){
      value = "BLUE";

      
      }else if(value == "BLUE") {
        value = "RED";

        }  
  }

  Serial.println(value);
}

so i want the button to change between the values but when i press the button it get crazy how can i fix that i know the problem and it is the value changes alot while i am pressing but how can fix this

Delta_G:
Look at the "State Change Example" and learn how to react once to a button becoming pressed instead of continuously as long as it is pressed.

Thanks for the help
