No additional info.

no particular reason but there was a mistake in my approach.I I tried to power all my sensors and lcds from a different power source without common ground. I had no idea about common ground. Then there was no output in my display and no data came from sonar sensors. That's why I tried to power up all my sensors and display from the nodemcu board. Then my nodemcu board was failed to supply the power I need, which is my mistake and my lack of knowledge. Then I decided to power them from arduino uno. But from blynk forum I realized that this is not the problem of my board, the problem is in my power structure.
