Wow! Thank you very much!
The only thing I didnt understand much, is the part of the web server. I think im going for Arduino to have it, because I dont want any PC's involved in the project. I want it to be very simple, just the arduino i will need to hook up into the equipment (speakers, etc) and the app to control it. I guess it will be more complicated. If im wrong, let me now, i'm new to all of this.
Thanks!!!
