Instead of writing hundreds of lines of code to handle Wi-Fi handshakes, timeouts, and data packets, this library allows you to connect your device to the internet using just a single line of code: Blynk.begin() . Why Do You Need the Library ZIP File? blynksimpleesp8266 h library zip
To get stable, packaged builds, download the compiled archives from the Blynk Library Releases Page. #include <ESP8266WiFi
BLYNK_WRITE(V1) int pinValue = param.asInt(); // Do something with the incoming data BLYNK_WRITE(V1) int pinValue = param

John uploaded the code to his ESP8266 module and configured the Blynk mobile app to connect to his project. He created two virtual pins, V1 and V2, to receive temperature and humidity data, respectively. He also set up a simple dashboard with two gauges to display the data.
