一開始用這個程式碼配上可變電阻(旋鈕)

接上5V,A0,GND

就可以發出聲音

-----

程式碼:

#define buzzer 2

#define buzzer 8

void setup() {

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

pinMode(13,OUTPUT);

pinMode(8,OUTPUT);

}

void loop() {

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

int now = analogRead(A0);

tone(8,now);

}

-----

這個程式碼可以讓燈隨著旋鈕變多變少

-----

程式碼:

void setup() {

  for (int i = 2; i <= 13; i++) {

    pinMode(i, OUTPUT);

  }

}

void loop() {

  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);

  }

}

-----

一樣是控制燈多少

可以配合joystick改變

-----

程式碼:

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);

}

紅色進度條多少

Processing程式碼:

import processing.serial.*;

Serial myPort;

void setup(){

 size(700,100);

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

}

int level=0;

void draw(){

 background(255);

 fill(255,0,0);

 rect(0,0,level*50,100);

 if( myPort.available()>0){

  int now = myPort.read();

  if(now=='A') level=0;

  if(now=='B') level=1;

  if(now=='C') level=2;

  if(now=='D') level=3;

  if(now=='E') level=4;

  if(now=='F') level=5;

  if(now=='G') level=6;

  if(now=='H') level=7;

  if(now=='I') level=8;

  if(now=='J') level=9;

  if(now=='K') level=10;

  if(now=='L') level=11;

  if(now=='M') level=12;

  if(now=='N') level=13;

 }

}

or

import processing.serial.*;

Serial myPort;

void setup(){

 size(700,100);

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

}

int level=0;

void draw(){

 background(255);

 fill(255,0,0);

 rect(0,0,level*50,100);

 if( myPort.available()>0){

  int now = myPort.read();

level = now-'A';

 }

}

-----

Processing 更精簡靈活的程式碼

-----

  import processing.serial.*;

  Serial myPort;

  void setup(){

   size(700,100);

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

  }

  int level=0;

  void draw(){

   background(255);

   fill(255,0,0);

   rect(0,0,level*3,100);

   if( myPort.available()>0){

    int now = myPort.read();

    level = now;

   }

  }

-----

Arduino版本

-----

程式碼:

void setup() {

  for (int i = 2; i <= 13; i++) {

    pinMode(i, OUTPUT);

  }

Serial.begin(9600);

}

void loop() {

  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(('A'+level));

Serial.write(level);

delay(20);

}
