使用PIR运动传感器Ardunio播放视频和处理

Question

处理草图效果很好，我可以从HDD播放视频，并且当PIR运动传感器检测到我的运动时，但实际上我想从PIR运动传感器触发视频或处理草图。我还用Arduino led引脚测试了运动传感器，当PIR传感器检测到运动时，它会闪烁。

如何将这两个草图相互连接，并且可以在“处理”中使用运动传感器播放任何视频文件。 谢谢！

int ledPin = 13;                // choose the pin for the LED
int inputPin = 3;               // choose the input pin (for PIR sensor)
int pirState = LOW;             // we start, assuming no motion detected
int val = 0;                    // variable for reading the pin status
 
void setup() {
  pinMode(ledPin, OUTPUT);      // declare LED as output
  pinMode(inputPin, INPUT);     // declare sensor as input
 
  Serial.begin(9600);
}
 
void loop() {
  val = digitalRead(inputPin);  // read input value
  if (val == HIGH) {            // check if the input is HIGH
    digitalWrite(ledPin, HIGH);  // turn LED ON
    if (pirState == LOW) {
      // we have just turned on
      Serial.println("Motion detected!");
      // We only want to print on the output change, not state
      pirState = HIGH;
    }
  } else {
    digitalWrite(ledPin, LOW); // turn LED OFF
    if (pirState == HIGH) {
      // we have just turned of
      Serial.println("Motion ended!");
      // We only want to print on the output change, not state
      pirState = LOW;
    }
  }
