Arduino操作启用/禁用开关或引脚

我的论文需要一些帮助 . 我完成了开关1,2和3的操作 .

如流程图所示，我需要禁用开关2和3，这样它就不会中断开关1的操作，也不会中断其他开关 . 然后我需要先打开开关1，然后在开关1操作结束后立即禁用开关1并启用开关2 .

启用开关2后，开关1和3应保持禁用状态，以便它不会中断开关2的操作，然后当开关2关闭时，应禁用它，然后启用开关3 .

启用开关3后，开关1和开关被禁用，因此我无法中断开关3的操作 . 关闭开关3后，它应该回到开始状态 .

我正在编写Arduino Mega 2560 .

这是我的代码

void loop() {
 // put your main code here, to run repeatedly:
 buttonState1 = digitalRead(buttonPin1);
 buttonState2 = digitalRead(buttonPin2);
 buttonState3 = digitalRead(buttonPin3);
if (buttonState1 == HIGH && buttonState2 == LOW && buttonState3 == LOW && counter == 1) {
plantMode();
} else if (buttonState1 == LOW && buttonState2 == HIGH && buttonState3 == LOW && counter == 2) {
maintenance();
} else if (buttonState1 == LOW && buttonState2 == LOW && buttonState3 == HIGH && counter == 3) {
harvestMode();
} else {
if (counter == 1) {
  lcd.setCursor(0, 0);
  lcd.print("   SWITCH  ON   ");
  lcd.setCursor(0, 1);
  lcd.print(" PLANTING  MODE ");
  digitalWrite(valve, HIGH);
  delay(500);
} else if (counter == 2) {
  lcd.setCursor(0, 0);
  lcd.print("   SWITCH  ON   ");
  lcd.setCursor(0, 1);
  lcd.print("MAINTENANCE MODE");
  digitalWrite(valve, HIGH);
  delay(500);
} else {
  lcd.setCursor(0, 0);
  lcd.print("   SWITCH  ON   ");
  lcd.setCursor(0, 1);
  lcd.print("  HARVEST MODE  ");
  digitalWrite(valve, HIGH);
  delay(500);
}
}
}

    制作一台状态机，每个按钮都有一个状态检查 .

    我没有编译代码，但我相信它会起作用 .

    int state = 1

void loop() {
  switch(state){
    case 1:
      if (digitalRead(buttonPin1)){
        plantMode();
        state = 2;
      }
      break;
    case 2:
      if (digitalRead(buttonPin2)){
        maintenance();
        state = 3;
      }
      break;
    case 3:
      if (digitalRead(buttonPin2)){
        maintenance();
      }
      else{
        state = 4;
      }
      break;
    case 4:
      if (digitalRead(buttonPin3)){
        harvestMode();
        state = 5;
      }
      break;
    case 5:
    if (digitalRead(buttonPin2)){
        harvestMode();
      }
      else{
        state = 1;
      }
      break;
  }   
  else{
    lcdPrint(state);
    delay(500);
  }
}

void lcdPrint(int state){
    lcd.setCursor(0, 0);
    lcd.print("   SWITCH  ON   ");
    lcd.setCursor(0, 1);
    switch(state){
      case 1:
        lcd.print(" PLANTING  MODE ");
        break;
      case 2:
        lcd.print("MAINTENANCE MODE");
        break;
      case 3:
        lcd.print("  HARVEST MODE  ");
        break;
      default:
        lcd.print("  UNKOWN MODE  ");
    }
    digitalWrite(valve, HIGH);
}
