Week12 芷萱的課堂筆記

利用Processing結合Arduino

1.首先在Processing中打入一小串程式碼

程式碼:

import processing.serial.*;

Serial myPort;

void setup(){

  size(400,400);

  myPort=new Serial(this,"COM7",115200);

}

void draw(){

  if(myPort.available()>0){

    String now =myPort.readString();

    println(now);

  }

}

2.建置環境-安裝驅動程式

控制台→裝置管理員

手動選擇路徑

選擇安裝即可

選擇相對應的COM即可

程式碼:

// Arduino pin numbers

const int SW_pin = 2; // digital pin connected to switch output

const int X_pin = 0; // analog pin connected to X output

const int Y_pin = 1; // analog pin connected to Y output

void setup() {

  pinMode(SW_pin, INPUT);

  digitalWrite(SW_pin, HIGH);

  Serial.begin(115200);

}

void loop() {

  Serial.print("Switch:  ");

  Serial.print(digitalRead(SW_pin));

  Serial.print("\n");

  Serial.print("X-axis: ");

  Serial.print(analogRead(X_pin));

  Serial.print("\n");

  Serial.print("Y-axis: ");

  Serial.println(analogRead(Y_pin));

  Serial.print("\n\n");

  delay(50);

}

3.

於Arduino中

程式碼:

// Arduino pin numbers

const int SW_pin = 2; // digital pin connected to switch output

const int X_pin = 0; // analog pin connected to X output

const int Y_pin = 1; // analog pin connected to Y output

void setup() {

  pinMode(SW_pin, INPUT);

  digitalWrite(SW_pin, HIGH);

  Serial.begin(115200);

}

void loop() {

  Serial.write(digitalRead(2));

  delay(50);

}

於Processing中

程式碼:

import processing.serial.*;

Serial myPort;

void setup(){

  size(400,400);

  myPort=new Serial(this,"COM7",115200);

}

void draw(){

  if(myPort.available()>0){

    int pin2=myPort.read();

    println(pin2);

    if(pin2==1)background(255,0,0);

  else background(255,255,0);

  }

}

4.

於Arduino中

程式碼:

// Arduino pin numbers

const int SW_pin = 2; // digital pin connected to switch output

const int X_pin = 0; // analog pin connected to X output

const int Y_pin = 1; // analog pin connected to Y output

void setup() {

  pinMode(SW_pin, INPUT);

  digitalWrite(SW_pin, HIGH);

  Serial.begin(115200);

}

void loop() {

  Serial.write(digitalRead(2));

  Serial.write(analogRead(A0)/4);

  Serial.write(analogRead(A1)/4);

  delay(50);

}

於Processing中

程式碼:

import processing.serial.*;

Serial myPort;

void setup(){

  size(400,400);

  myPort=new Serial(this,"COM7",115200);

}

void draw(){

  if(myPort.available()>0){

    int pin2=myPort.read();

    int x=myPort.read();

    int y=myPort.read();

    println(pin2);

    if(pin2==1)background(255,0,0);

  else background(255,255,0);

  ellipse(x,y,20,20);

  }

}
