Which of the two you want to connect the sensor to?
Actually it doesn't matter really - just take two pins, echo and trig, tell your sketch which ones you have, and you're good to go. Uses the exact same code for both processors.

Where do i program the code?? directly in esp8266 or in arduino uno board?

please help me this is a massive help in my thesis :frowning:

You normally program using an IDE such as the Arduino IDE, and then upload the compiled code onto the processor you want it to be on.
