 按joystick會變色

按下joystick發出聲音

void setup() 

{

  // put your setup code here, to run once:

  pinMode(2,INPUT_PULLUP);

  pinMode(8,OUTPUT);

}

int state=0;

void loop() 

{

  // put your main code here, to run repeatedly:

  if(digitalRead(2)==LOW)//當板上按鈕按下時或joystick按下時

    tone(8,2500,100); //發出聲音

  else

    noTone(8);

}

按下joystick用1、0表示有沒有按

void setup() 

{

  // put your setup code here, to run once:

  Serial.begin(9600);

  pinMode(2,INPUT_PULLUP);

  pinMode(8,OUTPUT);

}

int state=0;//開關狀態

void loop() 

{

  // put your main code here, to run repeatedly:

  if(digitalRead(2)==LOW && state==0)

  {

    state=1;//當按鈕按下去時

    Serial.write("1");

  }

  if(digitalRead(2)==HIGH && state==1)

  {

    state=0;//按鈕沒按時

    Serial.write("0");

  }

  delay(100);

}
