## Getting Started tutorials

* [Blynk + JavaScript in 20 minutes (Raspberry Pi, Edison, Espruino...)](http://www.instructables.com/id/Blynk-JavaScript-in-20-minutes-Raspberry-Pi-Edison/)
* [Raspberry Pi + DHT11/DHT22/AM2302](http://www.instructables.com/id/Raspberry-Pi-Nodejs-Blynk-App-DHT11DHT22AM2302/)

## Usage example
```js
var BlynkLib = require('blynk-library');

var blynk = new BlynkLib.Blynk('715f8caae9bf4a91bae319d0376caa8d');
var v1 = new blynk.VirtualPin(1);
var v9 = new blynk.VirtualPin(9);

v1.on('write', function(param) {
  console.log('V1:', param);
});

v9.on('read', function() {
  v9.write(new Date().getSeconds());
});
```

## Tested on:
* Node.js
 * Intel Edison
 * Desktop (Windows, Linux): TCP, SSL
* Espruino
 * Pico: ESP8266WiFi_0v25, over USB/Serial
 * VoCore (using OpenWRT Espruino package)
 * Linux

## Boards with supported direct pin IO:
* Intel Edison, Galileo using [mraa](https://www.npmjs.com/package/mraa) package
* Raspberry Pi, Beaglebone using [onoff](https://www.npmjs.com/package/onoff) package
* Espruino Pico
* OpenWrt + Espruino package

Just install the required package and this module will do auto-detection.
