 用joysick控制血條

arduino:

void setup() {

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

  for(int i=2;i<=13;i++){

    pinMode(i,OUTPUT);

  }

  Serial.begin(9600);

}

void loop() {

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

  int now = analogRead(A0);

  int level = now/4;

  for(int i=2;i<=13;i++){

    if(i<level) digitalWrite(i,HIGH);

    else digitalWrite(i,LOW);

  }

  Serial.write(level);

  delay(20);

}

processing:

import processing.serial.*;

Serial myPort;

void setup(){

  size(700,100);

  myPort = new Serial(this,"COM4",9600);

}

int level = 0;

void draw(){

  background(255);

  fill(0,50,200);

  rect(0,0,level*3,100);

  if(myPort.available()>0){

    int now = myPort.read();

    level = now;

  }

}

隨著按鈕改變英文字顯示不同:

void setup() {

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

  for(int i=2;i<=13;i++){

    pinMode(i,OUTPUT);

  }

 Serial.begin(9600);

}

void loop() {

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

  int now = analogRead(A0);

  int level = now/(512/13);

  for(int i=2;i<=13;i++){

    if(i<level) digitalWrite(i,HIGH);

    else digitalWrite(i,LOW);

  }

  Serial.write('A'+level);

  delay(100);

}

控制板子燈發光數量:

void setup() {

  for(int i=2;i<=13;i++)

  {

    pinMode(i,OUTPUT);

  }

  Serial.begin(9600);

}

void loop() {

  int now=analogRead(A0);

  int level=now/(1024/13);

  for(int i=2;i<=13;i++)

  {

    if(i<level)digitalWrite(i,HIGH);

    else digitalWrite(i,LOW);

  }

  Serial.write(('A'+level));

  delay(100);

}
