Can I have a node server and a device say my phone which sends data to the node server then the server sends it to the arduino, Wirelessly. Also is it possible to do the reverse, that is the Arduino sending the data to the server and the server to my phone(via an app), also Wirelessly. Here by wirelessly I mean by usinh wifi or something and NOT THE BLUETOOTH. This maybe a really noob Question, but I am a total beginner in this!!! Would really really be helpful if you reply!
@Bryant11 Welcome to the forum. The answer to your questions are yes and yes. You can use an ethernet shield to connect your network and connect your phone via WiFi to send data back and forth to the Arduino.
