Question

我正在尝试组建一个双人游戏，需要对视觉进行音频反射。通过使用littebits声音触发声音输入和littbits arduino将其连接到计算机。但我是新手，并且不知道如何将arduino连接到处理并使用声音触发器的输入来在出现黑色方块时实现分数。

这是我处理的代码和我从littlebits网站上获取的示例arduino代码，并试图修改一下。

提前谢谢！

你需要两段代码才能工作：一个在发送命令的Arduino上，一个用于处理接收和解析这些命令。

我没有使用过littlebits模块，但这是this very detailed tutorial的按钮示例。

Arduino代码：

int switchPin = 4;               // switch connected to pin 4 

void setup() { 
  pinMode(switchPin, INPUT);     // set pin 0 as an input 
  Serial.begin(9600);            // start serial communication at 9600bps 
} 

void loop() { 
  if (digitalRead(switchPin) == HIGH) {  // if switch is ON, 
    Serial.print(1, BYTE);               // send 1 to Processing
  } else {                               // if the switch is not ON,
    Serial.print(0, BYTE);               // send 0 to Processing 
  } 
  delay(100);                            // wait 100 milliseconds 
}

匹配的处理代码：

import processing.serial.*; 

Serial port;            // create object from Serial class 
int val;                // data received from the serial port 

void setup() { 
  size(200, 200); 
  frameRate(10); 

  // open the port that the board is connected to
  // and use the same speed (9600bps) 
  port = new Serial(this, 9600); 
} 

void draw() { 
  if (0 < port.available()) {        // if data is available,
    val = port.read();               // read it and store it in val
  } 
  background(255);                   // set background to white
  if (val == 0)  {                   // if the serial value is 0,
    fill(0);                         // set fill to black
  } else {                           // if the serial value is not 0,
    fill(204);                       // set fill to light gray
  } 
  rect(50, 50, 100, 100);
}

请注意，Arduino发送一个Processing查找和解释的值。您还可以查看Arduino IDE中的PhysicalPixel示例，以获取有关将数据从Processing发送到Arduino的示例。
