I am doing a project that use android app to control a robot via wifi communication with Ethernet shield and wifi router (TP-Link WR740N)
- Android app <-> wifi router (TP-link) <-> Arduino Ethernet Shield <-> Arduino Mega 2560.
But I don’t know how do they work? For example, how do the Ethernet Shield and Wifi router transfer data? (Ethernet shield have to play a role as a webserver or client?)
Anybody can help me deal with this project? any document or any turtorial?
Thanks a lot.
