johnny-five 到 arduino >>> 串口通信

Question

我是 johnny-five.js 框架的新手 (javascript-iot) 我想在 johnny- 中做一些 "hello world"五通过闪烁 arduino 板上的板载 LED，根据一些教程，板子默认为 pin 13，这是错误..

/home/botkiller/javascript/samplej5/node_modules/bindings/bindings.js:96 throw err ^

Error: Could not locate the bindings file.

(/home/botkiller/javascript/samplej5/node_modules/serialport/lib/bindings/auto-detect.js:16:22)

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-5 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);
    });

});

Answer 1

我通过 linuxbrew 下载了 npm 和 node.js，但我安装它们 而不是在根 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。
