if (750 < value < 900)
  {
    digitalWrite(6, HIGH);
    delay(5);
    digitalWrite(6, LOW);
  }

i want to work this code when i push the button

if ((buttonState == HIGH) && (750 < value < 900))
  {
    digitalWrite(6, HIGH);
    delay(5);
    digitalWrite(6, LOW);
  }

but it dosn't work how can i solve this

at excel i do like this =IF(B3=1;A32,05;IF(B3=2;A31,3;"")) is this work same as arduino

thank you

if ((buttonstate == HIGH) && ((750 < value) && (value < 900)))

Almost.
This is wrong though:

(750 < value < 900)

that will test if 750 is less than value - if it is, the (750 < value) will be 1 else 0. And either way, 0 or 1 are both lower than 900, so that will always return true.

(750 < value) && (value < 900)

You may have to deal with debouncing the switch (there's lots of material on this around the web), depending on your use case.

thank you for your help

it worked !

this my final codes

int sensorPini = A0;
int olculenIsikDegeri = 0;

int butonPini = 4;
int butonDurumu = 0;


void setup() {
  
  pinMode(4, INPUT);
  //Serial.begin(9600);
  pinMode(13, OUTPUT);
  pinMode(1, OUTPUT);  
  pinMode(2, OUTPUT);       
  pinMode(3, OUTPUT);  
  pinMode(4, OUTPUT);  
  pinMode(5, OUTPUT);  
  pinMode(6, OUTPUT);  
  pinMode(7, OUTPUT);  
  pinMode(8, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
}


void loop() {
  
  butonDurumu = digitalRead(butonPini);
  olculenIsikDegeri = analogRead(sensorPini);
  if (butonDurumu == LOW)
  {
  digitalWrite(3, HIGH);
  digitalWrite(13, HIGH);
  digitalWrite(5, HIGH);
  digitalWrite(6, HIGH);
  delay(1000);              
  digitalWrite(3, LOW);
  digitalWrite(13, LOW);
  digitalWrite(5, LOW);
  digitalWrite(6, LOW);
  delay(1000);
  }
  if ((butonDurumu == HIGH) && ((355 < olculenIsikDegeri) && (olculenIsikDegeri < 500)))
  {
    digitalWrite(6, HIGH);
    delay(1);
    digitalWrite(6, LOW);
  }
  if ((butonDurumu == HIGH) && ((210 < olculenIsikDegeri) && (olculenIsikDegeri < 355)))
  {
    digitalWrite(5, HIGH);
    delay(1);
    digitalWrite(5, LOW);
  }
  if ((butonDurumu == HIGH) && ((110 < olculenIsikDegeri) && (olculenIsikDegeri < 210)))
  {
    digitalWrite(3, HIGH);
    delay(1);
    digitalWrite(3, LOW);
  }
  //if (butonDurumu == HIGH)
  {
    //Serial.println(olculenIsikDegeri);
  }
}
