Interfacing esp8266-01 with arduino nano

[tapu]

Hello friends ,
I want to connect gpio of esp8266-01 to any gpio pin of arduino nano.that means i want to control arduino nano by wifi network.here i can write arduino code.but my issue is how to design circuit for both microcontroller. Because esp01 operate in 3.3v and arduino nano requires 5v.please guide.
Thanks
Tepu

Hi,

It all depends on the input threshod levels for HIGH and LOW at the according pins. And the according output levels.

I don´t like reading the datasheets for you . So please do on your own.
Look in the electrical specification section for V_OL, V_OH, V_IL, VIH ... for normal/your operation condtions.
Report them to us. (This makes 8 values in total for 2 microcontrollers)

*****
A sketch of the schematic would be helpful ... to show what you want to do.

*****
Also you don´t give any idea of
* the interface you want to use
* one direction / bidirectional data flow
* data rate
* distance between ESP and AruinoNano
* and so on..
