[ESP8266/ESP32] 基于wifi实现的人体感应视频播放

采用的是esp32芯片和红外传感器，制作的硬件

/*
 *  This sketch sends a message to a TCP server
 *
 */

#include <WiFi.h>
#include <WiFiMulti.h>

WiFiMulti WiFiMulti;

int k=1;

void setup()
{
    Serial.begin(115200);
    delay(10);
    pinMode(0, INPUT); 
    // We start by connecting to a WiFi network
    WiFiMulti.addAP("xxxx", "xxxxxxx");

    Serial.println();
    Serial.println();
    Serial.print("Waiting for WiFi... ");

    while(WiFiMulti.run() != WL_CONNECTED) {
        Serial.print(".");
        delay(500);
    }

    Serial.println("");
    Serial.println("WiFi connected");
    Serial.println("IP address: ");
    Serial.println(WiFi.localIP());

    delay(500);
}


void loop()
{
//    const uint16_t port = 80;
//    const char * host = "192.168.1.1"; // ip or dns
    const uint16_t port =10002;
    const char * host = "192.168.1.102"; // ip or dns

    Serial.print("Connecting to ");
    Serial.println(host);

    // Use WiFiClient class to create TCP connections
    WiFiClient client;

    if (!client.connect(host, port)) {
        Serial.println("Connection failed.");
        Serial.println("Waiting 5 seconds before retrying...");
        delay(5000);
        return;
    }

    // This will send a request to the server
    //uncomment this line to send an arbitrary string to the server
    //client.print("Send this data to the server");
    //uncomment this line to send a basic document request to the server
    //client.print("GET /index.html HTTP/1.1\n\n");
    if(k!=digitalRead(0))
    {
      k=digitalRead(0);
    client.write(k); 
    }
  int maxloops = 0;

  //wait for the server's reply to become available
  while (!client.available() && maxloops < 1000)
  {
    maxloops++;
    delay(1); //delay 1 msec
  }
  if (client.available() > 0)
  {
    //read back one line from the server
    String line = client.readStringUntil('\r');
    Serial.println(line);
  }
  else
  {
    Serial.println("client.available() timed out ");
  }

   // Serial.println("Closing connection.");
   // client.stop();

    //Serial.println("Waiting 5 seconds before restarting...");
    //delay(5000);
}

然后用processing做个服务器加播放软件

import processing.net.*;
import VLCJVideo.*;

VLCJVideo video;
int whatClientSaid=1;
PImage img;

int port = 10002;       
Server myServer;        

void setup()
{  
  fullScreen();
  noStroke();
   
  video = new VLCJVideo(this);
  video.open("1.mp4");
  video.play();
  
  img = loadImage("1.jpg");
 
  
  myServer = new Server(this, port);
}

void draw()
{
  // Get the next available client
  Client thisClient = myServer.available();
  // If the client is not null, and says something, display what it said
  if (thisClient !=null) {
     whatClientSaid = thisClient.read();
    //if (whatClientSaid != null) {
      println(whatClientSaid);
    //} 
  } 
  image(img, 0,0);
  if(whatClientSaid==0){
  image(video, 0, 0, width, height);
  if(video.isStopped()) video.play();
  }
  
  
}
