Wiring multiple devices to Arduino through SPI

I am a totaly newbie about Arduino and electronics.I have a question about wiring multiple SPI devices and Arduino.

http://www.eeherald.com/section/design-guide/esmod12.html

On this page there is a diagram under "Independent slave configuration" title .Looks like each wire(other than ss,cs) is connected to more than one device.Which type of wires are they,how are they connected to more than one device?

For prototyping, I prefer stuff like this. Already assembled and ready to go.

I use jumper wires like these. Male-to-male is what I use the most of. http://www.adafruit.com/categories/125

Combine those with a breadboard like one of these. http://www.adafruit.com/categories/124

Mix and match. :)

Thanks for your answer.I looked at the pictures on your links. Is it breadboard which allows to connect more than one wire to same(one) pin on Arduino?

Yes. You can make your own wires if you prefer, but for prototyping (testing) I prefer a breadboard for that.

Thanks for your answer.

the MISO/MOSI and slk can be multipule used, which the "SS" is the slave-select, to select which slave module the microcontroller want to communicate with...

Thanks for your answer.

the MISO/MOSI and slk can be multipule used, which the "SS" is the slave-select

Could you explain "multiple using " of MOSI MISO and slk a bit more?(is it about wiring?)

MOSI, MOSI and SCK are all connected together, on every device connected to the bus. The master then activates a CS/SS signal for each slave when it wants to talk to that slave.

So,for connecting them we need custom wires or breadboard ,right? (sorry I’m a newbie and seems like it is much more risky to do something with Arduino than programming on a computer,so I ask to be sure that I understood right)

Yes you need to organise your own wiring, either with a breadboard or whatever method is easiest.

And yes, working with embedded processors is more "dangerous" in that you can easily blow up something. That said chips are usually pretty robust and you have to do something really stupid or be unlucky to do real damage.
