Welcome, you will need a decent understanding of C/C++ and Arduino IDE to use Blynk.

There are plenty of examples available for you to learn from.

@sskaa You have already asked for code in a previous topic, but here is the same answer, again :stuck_out_tongue_winking_eye:

Welcome to Blynk,

Aside from the Blynk Developers, who are busy developing, :wink: we are all fellow Blynk users who are volunteering our time here, so we generally will not write your code for you.

But as you start learning and need clarification on various Blynk commands or some suggestions with your own programmed sketch, then we will help as best able.

Start with the basics and load in some examples from the Sketch Builder (Link is in the upper right of this page), and read through the Documentation (Link is also in the upper right of this page).

Happy Blynking!
