Windows Arduino编程故障

我正在学习如何使用Arduino，当然，我尝试运行的东西不会起作用。我确实遇到了驱动程序方面的问题，我已经解决了，并且重新安装了Arduino软件。我还是不能让它正常工作。我的电脑识别出Arduino已连接

这就是我想要做的。我让班上的其他人看了我的代码，甚至他都说我的代码是正确的。我不确定我做错了什么，我真的需要让这件事在课堂上发挥作用。我在这一点上感到非常沮丧

int ledPin = 13;
int Dtime = 100;
void setup() {
pinMode(ledPin, OUTPUT);  // put your setup code here, to run once:

}

void loop() {
  digitalWrite(ledPin, HIGH);
  delay(Dtime);
  digitalWrite(ledPin, LOW);
  delay(Dtime);
  // put your main code here, to run repeatedly:

}

我想您需要获得最新版本的java。更新您的JRE，从

下载最新版本，您发布的问题似乎与IDE设置/配置有关，而与您的程序无关。因此（

EditorToolbar.mousePressed（EditorToolbar.java:349）

）我有一种印象，当IDE试图将程序发送到Adruino或编译时——在您按下工具栏上的按钮之后——IDE失败了。可能编译器和工具没有安装在Arduino IDE寻找它们的位置？
