hi how can i get data from arduino and save it in table in "ms.access" data base using WIFI ?
Easiest way is to have a program running on the PC that opens a socket and wait s for connection from the Arduino. Then the Arduino can post its measurements to that application, and that application takes care of writing it to ms.access.
Access supports VBA so it even might be possible to open a socket in VBA. Technically you can start anything from VBA but far from trivial.
