3.How to install library
- http://help.blynk.cc/en/articles/512105-how-to-install-blynk-library-for-arduino-ide
- To install a new library into your Arduino IDE you can use the Library Manager (available from IDE version 1.6.2). Open the IDE and click to the "Sketch" menu and then Include Library > Manage Libraries.
- Then the Library Manager will open and you will find a list of libraries that are already installed or ready for installation. Search for Blynk library and in the version selection choose the latest version to date
- Finally click on Install and wait for the IDE to install the new library. Downloading may take time depending on your connection speed. Once it has finished, an Installed tag should appear next to the Bridge library. You can close the library manager.
- You can now find the new library available in the Sketch > Include Library menu.
- If "fatal error: version.h: No such file or directory", most probably you have outdated Arduino Core for ESP8266. Please update
