What I want to build is basically a switchboard (SB) for controlling light, fan, TV etc. The SB will be controlled from a smartphone. Both the SB and the Smartphone will be connected to the same network through a WiFi router. The smartphone will send commands using an app, and the switchboard will respond accordingly.
I decided to build this system using an arduino. But I'm confused which model should I use, and which other components will be required (for example, to connect the SB to the router). I want it to be low-cost.
Please help me.
