** Preamble (ignore this if you want to) **
** Actual topic **
I'd like to build my brother a simple system that controls a fan on his heating system. It should be a fairly simple project. Based upon a certain temperature I want to be able to turn on an AC fan. The fan is fairly low wattage (http://www.princessauto.com/pal/product/0772889/Single-Speed/8%22-Duct-Booster-Fan). The only part right now that I'm confused about is how do I piece this all together?
- What do I put the Arduino actually in? Is there some common Arduino housings that people use?
- What Power Source will I need to use? Can I use 1 power source for the Arduino and the Fan?
- How do I switch on 120v devices? Is there a simple cheap relay that would work for this?
- How will I adjust when I want the fan to come on (like at what temp) and would I see what temperature it is. Would I need and LCD screen? Buttons to modify some settings?
I know there will be many solutions to each part so I'm just asking you to let me know how would you do all of this and why.
I thank yee in advanced.
