Hi, all! I'm planning to build a home automation system of my own. I've been told that PICs would be great for this. I plan to use RS-485 bus to connect PICs together. Is this a good choice? For several weeks I have tried to document my ideas and today I started translating the document into English. It can be found at http://www.plopcrew.net/vuori/talo/ha.html However, I'm _new_ to PICs and electronics, so I would like to ask if anyone of you has done something similar. I would be pleased if you had some ideas or appropriate links (especially for circuits). Any kind of help would be greatly appreciated. I hope I'll some day get this finished and documented so that others can benefit, too. I think the programming is not that bad for me, as I know C and have done some Z80 asm programming, too. Sorry for my bad English. Please ask, if this email or the web page mentioned is unreadable or not understandable.
