push button and limit switch

Projects Programming
1

Hi,
ı made a project with push button,limit swwitches and dc motors.I want to start calibration process when first push button pressed and stop calibration process first push putton press secondly. But when i pressed first push button serial monitor didnt write "calibration start".

if(kalibrasyonState == HIGH && lastkalibrasyonState == LOW){
 Serial.println("calibrasyon start");
 vanapositioncontrol();
 int vanarole2State = digitalRead(vanarole2);
 if(vanarole2State==HIGH){
     Serial.println("vana pozsiyon kontrol edildi");
   tartipositioncontrol();
}
int tartirole1State = digitalRead(tartirole1);
   if(tartirole1==HIGH){
 Serial.println("tartı pozsiyon kontrol edildi");
     calibration();
     Serial.println("kalibrasyon tamamlandı");
     }
     }
     lastkalibrasyonState=kalibrasyonState;

Full code of project is here.

(Put your code under code brackets)

  pinMode(kalibrasyon, INPUT);
   pinMode(process, INPUT);
     pinMode(vanarole1, INPUT);
       pinMode(vanarole2, INPUT);
         pinMode(tartirole1, INPUT);
           pinMode(tartirole2, INPUT);

Is
there
something
wrong
with
your
tab
key?

How IS your switch wired?

4

one of leg of button connect to 5v other leg is connected to arduino pin and ground with 10 k resistor

5 
const int button2Pin = 2;     // the number of the pushbutton pin
const int ledPin =  13;      // the number of the LED pin
int ledState = LOW;         // the current state of the output pin
int lastButtonState = LOW;   // the previous reading from the input pin
void setup() {
 pinMode(button2Pin, INPUT);
 pinMode(ledPin, OUTPUT);
}
void loop() {
int reading = digitalRead(button2Pin);
if (lastButtonState == LOW && reading == HIGH)
{
if (ledState == HIGH) 
{
ledState = LOW;}

else {
 ledState = HIGH;
}
digitalWrite(ledPin, ledState);
}
lastButtonState = reading;
}

this code is working with my button wiring and button act as a switch but similar code and wiring in above didnt work

one of leg of button connect to 5v other leg is connected to arduino pin and ground with 10 k resistor

This conveys so little information as to be nearly useless.

Wiring a switch using the internal pullup resistor is so much simpler. One leg to ground. The other leg to a digital pin. No ambiguity. HIGH means not pressed; LOW means pressed. After you enable the internal pullup resistor, anyway.

I don't speak the same language but I used ctrl+t and notice some interesting open and closing switchs in the real program

I have made notes in the program section that may assist

 if (kalibrasyonState == HIGH && lastkalibrasyonState == LOW) {//open if
    if (kalibrasyonState == HIGH ) {
      kalibrasyonState = LOW;
    }//nope thats a work around because its in a if so it wont do that
    else {
      kalibrasyonState = HIGH;
      Serial.println("kalibrasyon başladı");
      vanapositioncontrol();
      int vanarole2State = digitalRead(vanarole2);
      if (vanarole2State == HIGH) {
        Serial.println("vana pozsiyon kontrol edildi");
        tartipositioncontrol();
      }
      int tartirole1State = digitalRead(tartirole1);
      if (tartirole1 == HIGH) {
        Serial.println("tartı pozsiyon kontrol edildi");
        calibration();
        Serial.println("kalibrasyon tamamlandı");
      }
    }//close  else 
    lastkalibrasyonState = kalibrasyonState;//what am i doing here
    //i can block the code on the first pass then im blocking this line
    //from ever reseting as lastkalibrasyonState will never go low
    
    paketboyutu = GetNumber();
    Serial.print("paketboyutu:");
    Serial.println(paketboyutu);
    double weight = scale.get_units(10);
    Serial.print("paketboyutu:");
    Serial.println(paketboyutu);
    // display.showNumberDec(weight);
    int processState = digitalRead(process);
    if (lastprocessState  == HIGH && processState  == LOW) {
      Serial.print("PROCESS BAŞLADI");
      while (weight < paketboyutu) { //İF Mİ WHİLE MI??
        vanageri();  //vana açılacak
      }
      vanapositioncontrol();
      int vanarole2State = digitalRead(vanarole2);
      if (vanarole2State == HIGH) {
        menteseac120();
        tartipositioncontrol();
      }
    }
    lastprocessState = processState;

  }//close  if (kalibrasyonState == HIGH && lastkalibrasyonState == LOW)
  
}
//think it should be 
//if (kalibrasyonState == HIGH && lastkalibrasyonState !=kalibrasyonState){
//do this once}

// in main loop after this 
//lastkalibrasyonState = kalibrasyonState;
