That loosened the knot in my head, I thought too complicated - thank you!
Anna is simply beautiful, I like her voice and her English. And Blynk is extremely practical, will save me a lot of time.

Hi, great video! Thanks for sharing. I am starting to work with blink and nodemcu now. One thing that took my attention. You comment that if I put those send functions inside loop method I can break my hardware! Can you please explain a bit more about this? Thank you

[mkstudio-tech]

Wonderful and how to use pinValue as a loop function
?

[denishd]

Excellent video!
Make a video, about advanced programming with blynk libraries. :D

[bhagirathshekhawat]

You are so beautiful and technically sound. Thanks for explaining Blynk app usage. I made my 8 zone Sprinkler system using it.

[ajitdhatrak]

Really it was great to know about virtual pins in Nodemcu. I am having a question related to Blynk. If I can define a group of buttons? suppose I am having eight relays and I need to operate 1, 3, 7 in one click if it is possible? I may need any combination. Can we define a group of buttons as Alexa can do it? or I need to write separate code for it?

[bibhutibhusanbehera]

What ever you did in this video, can it possible to make reverse.I mean if I do some thing in hard ware it show in my blynk app.

[kenwayjohn]

what is the difference in virtual pin write, read and reply? do I need to use only write?

[bhagirathshekhawat]

I have on off switch but I want to add off timer on each on/off button, please tell me how can I do that in Blynk app. I will buy credit for adding more buttons
