/************************************************************* Download latest Blynk library here: https://github.com/blynkkk/blynk-library/releases/latest Blynk is a platform with iOS and Android apps to control Arduino, Raspberry Pi and the likes over the Internet. You can easily build graphic interfaces for all your projects by simply dragging and dropping widgets.

Set any reading frequency (i.e. 1 second) *************************************************************/ /* Comment this out to disable prints and save space */ #define BLYNK_PRINT Serial #include #include #include // You should get Auth Token in the Blynk App. // Go to the Project Settings (nut icon). char auth[] = "YourAuthToken"; // Use Virtual pin 5 for uptime display #define PIN_UPTIME V5 // This function tells Arduino what to do if there is a Widget // which is requesting data for Virtual Pin (5) BLYNK_READ(PIN_UPTIME) { // This command writes Arduino's uptime in seconds to Virtual Pin (5) Blynk.virtualWrite(PIN_UPTIME, millis() / 1000); } void setup() { // Debug console Serial.begin(9600); Blynk.begin(auth); } void loop() { Blynk.run(); }
