Blynk is an easy to use app builder that allows users to add a variety
of buttons, sliders, graphical displays and even RGB controllers to
their phone. The SparkFun Blynk Board is specially designed to work
with the 'widgets' within the Blynk mobile app to create your next IoT

Monitor local weather conditions, control LEDs from your phone, even
send a tweet when it's time to water your plants! Every Blynk Board
comes fully programmed and also includes a Blynk subscription code
card (15k Energy at a $10 value), which will be needed to connect the
Blynk Board to your Blynk account, connect to a Wi-Fi signal and you
are ready to start Blynking! You'll be controlling the Blynk Board
from half way around the world in no time.

On board every Blynk Board is the economic yet powerful ESP8266
framework that will allow you to connect to most 2.4GHz WiFi networks,
that are either open (no password) or protected with WPA, WPA-2, or
WEP authentication. The Blynk Board interfaces with the outside world
using input/ouput (I/O) "pins" that can either control real-world
objects, like motors or LEDs, or read in values from sensors (like
light or position). Each of the Blynk Board's pins are accessible via
the large, metal-encircled holes on the edge of the board. These large
holes are designed to interface with alligator clip cables - a staple
interface cable for beginner and advanced electrical engineer alike.
During setup, the RGB LED on the Blynk Board will be your window into
its soul. The board uses this multi-colored LED to indicate all sorts
of status modes including how to identify which board is yours.

Blynk is a digital dashboard for your iOS or Android device that
allows you to easily build graphical interfaces by dragging and
dropping widgets to control for your newest IoT projects! With the
Blynk app you will be able to control the Blynk board or any other
compatible hardware remotely by displaying sensor data, analyzing your
surroundings, activating a function of your project and much more.

Note: The Blynk app is compatible with iDevices running iOS 7.0+, and
Android's running any version above or equal to 4.0.
