How to bring arduino online?

Question

Android

I have an Arduino uno and an Ethernet shield What do I need to control the ports of the Arduino and get information about the status of these ports, for example, turn on the light and check whether it is on or off and receive data on temperature and humidity

Answer 1

To Uno - a humidity and temperature sensor (to analog or digital inputs), light - through a relay.
Shield - on Uno, Shield wire - to the router, and then a sketch of a simple server that receives requests.
