Node For MegaPi

How To Use

Compile and upload the Firmware to your MegaPi ( https://github.com/Makeblock-Official/FirmwareForMegaPi )
On your Raspberry Pi,
```
npm install megapi
```
Insert the initial code for starting MegaPi first.

var MegaPi = require("megapi").MegaPi;
var bot = new MegaPi("/dev/ttyS0", onStart); //"/dev/ttyAMA0" for rpi2, "/dev/ttyS0" for rpi3
function onStart(){
  //start your code
  setTimeout(loop,500);
}
var level = 0;
function loop(){
  bot.digitalWrite(13, level);
  level = 1-level;
  setTimeout(loop,500);
}

node your code
