先安裝驅動程式

配合搖桿 連接

接線

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(9600);

}

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(500);

}

移動搖桿會有不同數值

利用搖桿換顏色

程式碼

Processing

import processing.serial.*;

Serial myPort;

void setup(){

   size(400,400);

   myPort = new Serial(this, "COM6", 115200);

}

void draw(){

 if(myPort.available()>0){

    //String now= myPort.readString();

   // println(now);

  int pin2=myPort.read();

  println(pin2);

  if(pin2==1)background(255,0,0);

  else background(0,255,0);

 }  

}

Arduino:

// 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);

}
