light bulb control using raspberry pi

[stoica adrian]

Hi,
Me and a friend of mine we want to make this project. We want to control the luminosity of our bulb lightroom using a phone. We want to make this using a raspberry pi. I am a full time electronics tehician, he is an full time progamator, so all the programing softuare goes to him.

Fore the interface between raspberry pi and bulb i want to use this:

But i don't know how to make the interface between phone and raspberry pi.
ideas?

I'd use wifi as the easiest common protocol. Give the RPi a wifi adapter (or just use an RPi3 with it built-in), and then either use the phone talking directly talking to the Pi, or have both connecting to a common server. (The latter allows control from anywhere; the former is more appropriate for an in-house only.)

I've got a very low opinion of any instructable that suggests building mains projects on any type of perfboard without dedicating a whole step to ensuring creepage and clearance distances are adequate.  If someone builds this on matrix board that's got plated through holes or a top-side ground plane, it would be pretty dangerous.  I would also recommend using a Dremel cutting disk to slot the board directly under the Optocoupler to improve the creepage distance.
