Blynk itself is an application which lets you create an app to control Arduino, Raspberry Pi and the likes over the Internet. Supported on both iOS and Android, Blynk will get you online and ready for the Internet Of Your Things. With Blynk's digital dashboard, building an application is so easy. You can simply drag and drop widgets to build a graphic interface for your project.
The SparkFun Blynk Board is specially designed to work with the ‘widgets’ within the Blynk mobile app to create your next IoT project. 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.
With the Sparkfun Blynk Board you can monitor local weather conditions, control LEDs from your phone, even send a tweet when it’s time to water your plants. The Blynk Board can be interfaced with the outside world using the I/O pins that can either control real-world objects, like motors or LEDs, or read in values from sensors. The Blynk app plus Blynk board package lets you control hardware remotely, displays sensor data, analyzing your surroundings or even activate a function of your project and much more.
Every Blynk Board comes fully programmed and also includes a Blynk subscription code card, 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!
