Arduino project with blynk via usb

[PeteKnight]

@Alina

char auth[] = "a8q7LrCYekGdx8z2mWd0aJ7C6WxR275g";

Is this your auth token, or one that’s left over from somewhere else?

If you’re copy/pasting this data from the Blynk web console…

@Alina

#define BLYNK_TEMPLATE_ID           "TMPLxxxxxx"
#define BLYNK_DEVICE_NAME           "Device"
#define BLYNK_AUTH_TOKEN            "YourAuthToken"

then that line of code ought to be changed to:

char auth[] = BLYNK_AUTH_TOKEN;

Have you edited the USB connection script to connect to the Blynk IoT server by changing thois line:

set SERV_ADDR=blynk-cloud.com

to this:

set SERV_ADDR=blynk.cloud

Also, this is very bad…

@Alina

  // Setup a function to be called every second
 
timer.setInterval(2000L,senzorUmidSol);
delay(1000);
timer.setInterval(2000L, senzorNivelApal);
delay(1000);
timer.setInterval(2000L,senzorPicaturi);
delay(1000);
timer.setInterval(2000L,senzorDHT);
  delay(1000);

You should read the “Staggering Timers” section of this tutorial…

Using BlynkTimer or SimpleTimer

Many users seem to struggle with the basic concepts of using BlynkTimer in their projects, despite the excellent discussions and tutorials that exist on this forum, so I thought I’d write a guide that will hopefully help clarify things. It’s rather long, as it attempts to explain the reasoning behind why and how we use timers, and covers some more advanced subjects, but I’ve tried to organise it in a way that helps people to find answers to specific questions… Why use a timer at all? Let’s say …
