Help...what to buy?!

Projects General Guidance

Hi there, I am new in here...sorry if this it's the wrong section to put this!
But i need some help, I want to build a "server" to control things at home such as lights/doors and turn on and off the PC., what I needed was to know what to buy (arduino) which one and plus the respective modules in order to build this home system
This ill work with the arduino that run on 12 volts and putting relays to works with things in 220v.
I know welding, basic and purest strains of electronica, as well as programming, but do not like to program.

Thanks for everything and hope to hear from you soon.

Best regards,

(Probably explained myself badly, sorry about my English)

IMHO..

the Arduino you get depends on your needs for:

1.) How many I/O pins you need/want?
2.) How much memory you may need for your application

Which brings us to the next step.. you say 'SERVER'.. so I'm assuming this will be on-line.. and be able to be controlled over the internet/phone?

Arduinos run on 5v... but can handle the 12v at the regulator.. if thats what you mean by "Arduino that will run on 12v?"

IMHO..?!!? What is this?

Thanks for the quick reply,

1.) How many I/O pins you need/want?
I need at least 4 (1 Positive + 1 Negative) to command relay's

2.) How much memory you may need for your application
This I don't know because i don't have the program... :slight_smile:

Yes, it's the propose...to use with iphone.

Once again, thanks for the reply and help...I just need to know the hardware that i need to buy!

It will be easier to recommend hardware if you tell us exactly what you plan to control.

As stayed, as before... to turn on/off lights/doors, and turn on/off a PC. It's with relay's, powered with arduino and a external font with 220v.

Thanks!

Forgive me for being inquisitive, but exactly how do you intend turning a PC off/on... If you're thinking by just interrupting/restoring the 240v what else do you need to do?

I do know what needs doing. I'm trying to gauge what you think you have to do to turn a PC off and then back on.

Forgive me. maybe I as incorrect with you. What i am thinking about doing is a "simple" turn on/off a relay that interrupt a extra current (220v) it's possible?!
And later, command the arduino, with a iphone.

What a need it's some advice about what to buy and later how to program it.

Once again, my apologies and best regards.

Let me say, what you are intending to do is not a minor task!

Arduino programming aside, the iPhone (ios) programming is a whole other issue

If I were you, I'd start with just bouncing some led's on and off till you got comfortable with Arduino's flavor of C programming
