I recently downloaded Blynk and am simply trying to establish a connection between my board (Arduino UNO) and the app. I’m trying the Arduino_Serial_USB example sketch but can’t for the life of me get it to compile. I’ve tried reinstalling the libraries and my Arduino IDE. I’m including the code and error message, any help is appreciated.
