Hello , what cable do you recommned ? I will use a breadboard which supports (29-20 AWG). I think that 26 AWG cable will be more solid than 24, is there any difference ?? Thanks
26 is thinner than 24!
I've got a batch of single-strand insulated hookup wire that's 0.6mm, which is between AWG 22 and 23, and that's just thick enough to sit solidly in Arduino female headers (designed of 0.6mm square pins), so I'd go for AWG 24 or 22 rather than 26. For just breadboard use somewhat thinner would be fine.

oooooooh my gooood... how i messed it up ??? i looked it over wikipedia .... imagine... 
thanks a lot ! i will change the order and ask a 24 AWG thanks !

In the context of what you are doing it won't make any difference at all.
it will be too "fragile" ? do you recommend a 24 AWG ? i dont want to be afraid of making "air" with my hands to breadboard and arduino , in order not to disconnect cables...
do you recommend a 24 AWG
Well I would not recommend using solder less bread board in the first place, but there is little difference I would say.

i didn't understand , sorry my english is not very good
GrumpyMike is referring to the fact that solderless breadboards can sometimes be prone to errors....... 
As fas as your question goes.. the 'thicker' your wire..(lower gauge number) the more chance it will NOT fit in the breadboard holes..
for SOLDERLESS projects/dev.. I recommend SOLID CORE wire..
for soldering projects.. I recommend using stranded wire..
Breadboards are notoriously unreliable IMO and you can spend a lot of time chasing "bugs" that are just bad connections.
They also have a quite high capacitance, this can cause things that are wrong to work and things that are right to not work.
That said they are the easiest way to prototype, especially for a beginner.

24 + 26 AWG , fit in the holes , im sure , the cable is solid of course , but i think it will be too thin... and will go out from the holes with little movements....
So you recommend using strip board instead of breadboard ? and solder everything in place... right ?
I no longer prototype but go straight to a PCB. But I used breadboards for years (decades really) to good affect and they are easier than soldering onto strip board so I would say use breadboards for an initial pass at a design or if you just want to quickly experiment with a new chip etc.
Just be aware of their limitations, mostly WRT potentially unreliable connections.
Use strip boards if there's any chance the design will become permanent or if you want to use it somewhere off the workbench.

Thanks for the info , what about the cable ? 26 AWG is very thin and unstable for a breadboard ? Do you recommend buying a 24 AWG or 22 AWG instead ?

Only if it's multi-strand, not solid core.

I recommend spending $2 on some proper breadboard wires with pins on the ends.

I can't get wire with pins because the length is not standard in my project...
this is the cable i want to buy 3 wire 100' Twisted Cable - 3030_0 - Phidgets ....
That's twisted pairs by the look of it, of no benefit for breadboarding. It's also 100 feet, I've not used half that much in 30 years 
I've used packs like this in the past
22G guage and that's OK but a bit heavy at times so you could go down to 24. 26 may be too light but that's probably OK as well.

Put some solder on the end to join the strands together into something stiffer.
Ok i will cancel the order and i will buy a utp 24 AWG ..... thanks for the advice all of you
In my experience 24Ga. works the best. 22Ga is a 'bit' too big although it will work and 26Ga tends to be noisy because it rarely fits tightly... especially if the female has been "Stretched" by a standard Square Pin (.025" Sq). THere is a "Breadboard" style of PCB available from Adafruit that is unique. It has a standard breadboard hole pattern and bottom connectivity identical to a breadboard and it is gold plated too. Complete your breadboard and finalize positions of components and wiring them transfer the components, one at a time to the "PCB" and solder them down. The finished product is identical to the breadboard without the "Added" capacity of the wire clips proximity to each other. The boards come in 1/4, 1/2 and full size 830 point PCB's. 3 to a pack, white in color and IMO well worth the money for a one of a kind circuit. I bought 3 of the full sized boards and I will be using them for sensor mounting and interfacing to my various Arduino's. I can also solder headers to stack boards or whatever I need to Add to a design, like headers for radio's or GPS or ...

I picked up a bunch of new breadboards when I started messing with microcontrollers and I'm a bit surprised but I have very, very few problems with them. That could well change once they have 100,000 miles on them.
I've got about a half mile of CAT-5 cable around, so I use a lot of that (24 ga).
