I want to build my own house control system with an arduino, but first it's enough to open the door
I want it like that:
I have an arduino uno with an ethernet-shield connected to my network at home (Fritz!Box).
When I am in this network with my phone, I should be able to open the door with my smartphone via an android app that I have programmed. Can anyone please explain, how I can connect my phone to the arduino via Wifi/Lan
Thanks for answering,
PS: Please excuse my bad english, I am 14 years old and german.
