## 電磁閥
We are starting with the BareMinimum Sketch found in the IDE, it should look something like this:

void setup() {
  // put your setup code here, to run once.
}
 
void loop() {
  // put your main code here, to run repeatedly.
}

So first we will need a variable for the Arduino pin:

int solenoidPin = 4;    //This is the output pin on the Arduino we are using
 
void setup() {
  // put your setup code here, to run once.
}
 
void loop() {
  // put your main code here, to run repeatedly.
}

Next we need to set the Arduino pin to act as an output:

int solenoidPin = 4;    //This is the output pin on the Arduino we are using
 
void setup() {
  // put your setup code here, to run once.
  pinMode(solenoidPin, OUTPUT);           //Sets the pin as an output
}
 
void loop() {
  // put your main code here, to run repeatedly. 
}

Now that it is set as an output we can tell it what to do:

int solenoidPin = 4;    //This is the output pin on the Arduino we are using
 
void setup() {
  // put your setup code here, to run once.
  pinMode(solenoidPin, OUTPUT);           //Sets the pin as an output
}
 
void loop() {
  // put your main code here, to run repeatedly.  
  digitalWrite(solenoidPin, HIGH);    //Switch Solenoid ON
  delay(1000);                      //Wait 1 Second
  digitalWrite(solenoidPin, LOW);     //Switch Solenoid OFF
  delay(1000);                      //Wait 1 Second
}

So if we want the solenoid to allow water to flow, set the pin high. When you want the water to stop flowing, set the pin low. In this case it will turn the water on for 1 second and then off for 1 second, looping forever (or at least until it is unplugged!) This solenoid valve could easily be used with the flow meter featured in our last tutorial to create a system that only allows a certain volume of water to flow before shutting off.

const byte switchPin = 10;
byte oldSwitchState = HIGH; // initial condition

void setup ()

void loop ()
  {
  // see if switch is open or closed
  byte switchState = digitalRead (switchPin);
  
  // has it changed since last time?
  if (switchState != oldSwitchState)
    {
    oldSwitchState =  switchState;  // remember for next time 
    if (switchState == LOW)
       {
       Serial.println ("Switch closed.");
       }  // end if switchState is LOW
    else
       {
       Serial.println ("Switch opened.");
       }  // end if switchState is HIGH
    }  // end of state change
   
  }
