今日進度:

1.用makeruno連接搖桿產生不同頻率的聲音

2.用makeruno連接搖桿在不同位置量多少燈

3..用makeruno連接搖桿產生字母

4.用processing產生紅色不同長度的棒子

5.用processing產生紅色不同長度的棒子(更好)

⚠️注意事項:

1.記得匯入執行檔才能偵測

2.可變電阻不能直接接,還有不能放置過久

上面兩種方式可能造成冒煙或火災

1.程式碼:

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);

}

2.程式碼:

void setup()

{

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

 for(int i=2; i<=13;i++)

  pinMode(i,OUTPUT);

}

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);

  }

}

3.程式碼:

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/(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);

}

執行結果:

4.程式碼:

import processing.serial.*;

Serial myPort;

void setup()

{

  size(700,100);

  myPort = new Serial (this,"COM6", 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';

  }

}

執行結果:

5.程式碼:

import processing.serial.*;

Serial myPort;

void setup()

{

  size(765,100);

  myPort = new Serial (this,"COM6", 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;

  }

}

執行結果:
