Javascript Node.js不工作的Arduino

我正在做一个有Arduino Uno的项目，使用UDP连接，它会将数据发送到运行Node.js模块的Mac，以获取数据并打印出来

这是我的Arduino代码：

#include <SPI.h>
#include <Ethernet.h>
#include <EthernetUdp.h>
//Import the necessary packages.

byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED}; //Arduino's MAC address.
IPAddress IP(192, 168, 1, 152); //Arduino's IP address.
unsigned int arduinoPort = 8888; //Arduino's transmission port.

IPAddress recieverIP(192, 168, 1, 77); //Mac's IP address.
unsigned int recieverPort = 6000; //Mac's transmission port.

EthernetUDP udp;

int sensorPin = 2; //The pin on the Arduino the PIR sensor is connected to.
int sensorStatus; //The PIR sensor's status.

void setup()
{
    Serial.begin(9600);
    Ethernet.begin(mac, IP); //Starting the Ethernet functionality.
    udp.begin(arduinoPort); //Starting the UDP server's functionality.
}

void loop()
{
    Serial.println("YES");
    udp.beginPacket(recieverIP, recieverPort);
    udp.write("YES");
    udp.endPacket();
    delay(10);
}

当我运行代码时，终端中没有打印值。怎么了？谢谢。

您不应该将

dgram

socket的事件大写

消息

应该是

消息

监听

应该是

监听

这是一个很小的例子

var dgram = require("dgram");
var server = dgram.createSocket("udp4");

server.on('listening' /*Correct*/,function(){ 
 console.log("it fires"); 
});

server.on('Listening' /*Wrong*/,function(){
 console.log("it doesn't fire");
});

server.bind(6000);
