I had to connect my arduino far from my computer: about 10-15 meters.
Some electronics stores say that usb 5 meters cable can repeat signal (without external 9v)
Do I need those types of cable or can I buy two simples A female/male cable adaptator of 5 meters each one ?
Why don't you try with XBees? I'm not a fan of cables (and probably my brain not a fan of radio waves but anyway).
5m is maximum specified cable length for USB. You can use USB hubs as repeaters, maximum number of hubs to daisy-chain is 3 or 4, see USB spec for exact number. Anyway, you will need only 2 hubs to get 15m.
Cause it's more expensive ($20) that cable and I am not fan of radiowave for children.
So, I would like to buy cable to enable me to plug my arduino that will be outside my home.
And AWG24 wire cable too.
I f you know a shopping website that offers both those cables, I am interested.
no more idea even on e shop best price ot import from france.
You probably won't find an active cable for less than the cost of a HUB.
I have seen a man on the forum that talk about RJ45 convert extension:
so choices are:
1- USB activ extends cable (but it cost more often than usb hub )
2- USB Hub (about 15- 20$)
3- your solution :
Just tested with a USB > RJ45 > USB extender, 25 meters worked just fine.
Can you confirm that it is working with RJ45 at 20 meters and give me a link to a e-shop best price you usually buy ?
Thank you for all :)
Ethernet shield cost more than $20 and does it enable to upload sketch into arduino ?
I believed it enabled to communicate some information between PC arduino no ?
Do you have a prefered e shop that ship to FRANCE ?
I don't think that there is a cheaper option.
Yes, with the Ethernet library you can have two ways communications, but I suggest you to investigate Ethernet projects before you go any further if that's suitable for you.
I think that place ships everywhere. Otherwise Google "Buy Arduino Ethernet Shield".
Actually I have a based solution with temperature sensors, ultrasonic and relay command in a box with my arduino.
My goal is to put this box outside my home.
So I need the more efficient and low cost way to continue uploading and evolve programm from within my home.
Do you think Usb Hub should less work than ethernet or not ?
Problem that I see is that Usb Hub provide 4 slot and each one has consumption of current.
If you confirm me that I wil not have pb, I buy it (15$ in france) and that'is
What do you think about activ usb cable (selft powered) ?
For such cases there is dealextreme:
Will take a couple of weeks to arrive though.
Personally, I think is a bad idea to extend an USB cable outside of your house.
If something happens like humidity your computer is at risk.
Also, a RJ45 cable is less disruptive than 2 USB hubs.
Yes, your website seems cool but I don't need 100 meters extender of four usb ports.
I need only 15 meters max... It seems that constructors see large. Many ports and high distance.
Ideally I need 2 ports and 15 meters.... I am searching for that.
Do you confirm that putting hub with many ports (> 2) will not disturb addressing to Arduino Board
I am open to the RJ45 solution if it's low cost.
Maybe can I do
PC-->USB/RJ45 adaptator--->RJ45 wire---->RJ45/Usb B adaptator.
If it is more expensive, I will programm only on weather fine days avoiding humidity and hig level current problems.
You have to put an RJ45 cable between the two units as shown in the picture. which can be any length between 5 and 100 meters.
Or I can buy this http://www.dealextreme.com/details.dx/sku.42750
A simple powered usb hub. I put 2 usb cable of 5 meters and then I have my distance to upload my sketch no ?
You could buy a powered usb hub. I would buy that localy, maybe they even let you try it if it works. If not they let you return it.
I am in France so it has to work !
Nobody on this forum has already have this problem and test the same solution ?
I will recieve it in 14 days just before christmas, so I must be sure that it will work cause my arduino has to light up some exterior lights.
