  This example shows how LOW/HIGH event may be triggered from
  Blynk Server to Arduino at specific time.

  Timer widget works for ANALOG and DIGITAL pins also.
  In this case you don't need to write code.
  Blynk handles that for you.

  App project setup:
    Timer widget attached to V5 and running project.

Actually, it’s well known error. Power supply you’re using is not sufficient for esp32. It’s a thirsty beast.

I’m using the esp-32 connected to the PC via usb cable.
How could I feed so that it worked?

With proper external usb power supply. My ESP32 works fine on my laptop USB, though.

Thank you very much for your attention.

thank you…

I power mine (a Wemos Lolin32) with a 1A USB adapter… plus it has a small battery backup :wink:

:crazy_face:
perfect … this is already a level higher … one day I get there.

Small battery backup with 3.6V 10Ah LiFePo4 cell? It will last till doomsday :)))

It is running my Most Important Blynk Project of all Time… so it needs to last! :smiley:
