Connect Arduino to laptop Wireless card

Using Arduino General Electronics
1

Hi guys,
I'm new to the electronics world.
My question is pre explained on the topic's subject.
Is it possible to connect my laptop wireless card to the Arduino (UNO) so I can use to communicate wirelessly ?

Best regards.

No,
(99.99999% sure , but I do not know the details of your laptops wifi-card.)

If you have an old laptop you could use it as bridge between the serial of Arduino and its wifi card (add some clever python code)

Without a lot of work, I suspect you can't take a card from a laptop and use it on the Arduino.

However, there are ways to get the Arduino to communicate wirelessly:

  • Getting a wifi shield to plug into the Arduino. From what I've read, there are various limitations on its use (it can only be used with an available wifi infrastructure, and the software for the wifi shield uses up most of the Arduino's memory).
  • Get a bluetooth card/shield on the Arduino (and bluetooth on the laptop if it doesn't have buetooth)
  • There are various low power radio cards for Arduino, and you would have to get something that would let your laptop also communicate
  • Get a GPRS/GPM shield for your Arduino (GPRS/GPM are cell phone technologies, and you would have to be careful not to exceed your data plans monthly limits)

I use this card and I am quite happy with it: http://www.elechouse.com/elechouse/images/product/UART%20WiFi%20Transparent%20Module/User%20Manual-03_ENGLISH.pdf.
It interfaces with my Arduino 2560 through a USB interface (the card does the conversion) and it doesn't cost any precious ram. It can even be configured through its own http server.

kind regards,

Jos

Yeah, I supected that it was not possible x) But who knows :smiley:
I already knew about the shields (wifi, bluetooth, etc...) but since I have this card from my old computer I though I could give it some use x)
In that case I will buy either a shield or the card that JosAH said he uses, wich seems very good. thank you for the tip JosAh :wink:
And thank you all for the help XD
Kind regards,
Sammael

@Jos,
Interesting wifi - European reseller known?

has what you need even a UNO with it built in on the board (xinoRF)

Not that I know; I'm buying mine straight from China; it has a terrible manual (written in Chenglish, see the link in my previous reply :wink: note that this card uses the 802.11b/g protocol. It is easy to program by an Ardiuno itself and its antenna is great (> 15m indoors with concrete walls)

kind regards,

Could you tell me how can I use the GPRS shield to connect it to Arduino Uno and send a sms to it to make it do some function like 'Stop' ?!!.

Looks cool. I guess it's this one: http://kortlink.dk/aliexpress/dt2u

Can you elaborate on the use of it - and why do you need a USB host shield, when the module have a Serial UART interface ?

// Per.

My guess is it is possible.
However, you need the pin assignment of the module.
Have the same issue.
got this module from a HP laptop.
has a rtl8188ee chip.
but no datasheet about the module itself.
without the datasheet, no deal...
maybe this will help, just found it
