Using wifi on a pi
I am sure this has been done before but I wonder if anyone can guide me in a tutorial on how to use the built in wifi in my pi with a DIY Arduino nano and a wifi chip like an 8266 with a relay to turn on and off a socket. This will be my first project but I am lost as to whether i'll need voltage regulators or caps etc. I am sure I am in the wrong forum area etc. This is my first go at trying to figure this out. I love the site!
