Getting Started tutorials

• Blynk + JavaScript in 20 minutes (Raspberry Pi, Edison, Espruino...)
• Raspberry Pi + DHT11/DHT22/AM2302

Usage example

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 package
• Raspberry Pi, Beaglebone using onoff package
• Espruino Pico
• OpenWrt + Espruino package

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

Implementations for other platforms

• Arduino
• Particle
• Lua, OpenWrt, NodeMCU
• Python, MicroPython
• OpenWrt packages
• MBED
• Node-RED
