Dear pros,
I want to connect my esp8266 board not shield with my arduino uno r3. This case my arduino will be the main board and esp8266 will work as internet connector. I repeat , I want to use esp8266 board not wifi shield. How I can do this?
any particular reason to use the UNO?
the ESP8266 is a much more powerful device, has plenty of IO support and has onboard WiFi
connect all your IO devices to the ESP8266 and you no longer require the UNO

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.
Now I am trying to implement new power structure from 5v adapter with common ground.
I posted the same problem in Blynk forum.Here is the link
