Here are some common issues that you may encounter when using the Blynk Simple ESP8266 library:
Once installed, you must include the library at the very top of your sketch. Here is a standard template for using BlynkSimpleEsp8266.h : blynksimpleesp8266 h library zip
The Blynk platform, as a whole, is a revolutionary system that allows you to create apps for iOS and Android to control any hardware over the Internet. By simply dragging and dropping widgets, you can build graphic interfaces for all your projects directly on your smartphone. The library, originally authored by Volodymyr Shymanskyy, is the firmware side of this equation, providing the code your board needs to talk to the Blynk Cloud. The license is permissive, allowing for both personal and commercial use under the MIT License.
