我是 johnny-five.js 框架 (javascript-iot) 的新手，我想在 johnny-five 中做一些 “hello world”对于某些教程，开发板默认为引脚 13，这是错误..

我在我的板上上传了标准的 firmata 并安装了所有依赖项以使用 johnny-five 到 arduino ...
这是我的代码:
const j5 = require('johnny-five');
const board = new j5.Board();
board.on("ready", function(){
this.pinMode(13, 1);
this.loop(1000, function (){
this.digitalWrite(13, 1);
});
});
最佳答案
我通过 linuxbrew 下载了 npm 和 node.js，但我安装它们不是在 root 中。这是错误的原因，计算机无法与设备 (Arduino) 通信，因为您必须访问计算机的根库。
哈哈哈...
PS:感谢语法检查。我的英语真的不好。
