將目前最潮的 Node.js + Edison + REST API 簡單結合～點亮你的世界 如何使用 Node.js以及 REST API 請參考 [intel Edison] Node.js + intel Edison 快速實作 REST API

• Step 1. 準備所需要的裝置

  1.LED Socket Kit

  2.Seeed studio BASE SHIELD

  3.Edison

• Step 2. 初始化 所需要的 GPIO 腳位

var mraa = require('mraa'); //require mraa  
console.log('MRAA Version: ' + mraa.getVersion()); //write the mraa version to the Intel XDK console

//var myOnboardLed = new mraa.Gpio(5, false, true); //LED hooked up to digital pin (or built in pin on Galileo Gen1)
var myOnboardLed = new mraa.Gpio(5); 

myOnboardLed.dir(mraa.DIR_OUT); //set the gpio direction to output  

• Step 3. 初始化 Node.js 的 express 框架

var app = require('express')();  
var http = require('http').Server(app);  
.
.
.
http.listen(1339, function () {//指定為1339 Port  
    'use strict';
    console.log('listening on *:1339');
});

• Step 4.REST API

  1.開燈API:http://<Edison URL>:1339/open

  2.關燈API:http://<Edison URL>:1339/close

app.get('/open', function (req, res) {//開燈  
    'use strict';
    res.send(JSON.stringify({"type":"open"}));
myOnboardLed.write(1);  
});
app.get('/close', function (req, res) {//關燈  
    'use strict';
    res.send(JSON.stringify({"type":"close"}));
myOnboardLed.write(0);  
});

• Step 5. 使用Postman 測試

  1.開燈API:http://<Edison URL>:1339/open

  2.關燈API:http://<Edison URL>:1339/close

這樣才夠潮!!
