Hey,
For my current project, I need someway to wireless connect to the internet. is there something beyond the beethingy to do this? I just need to retrieve TCL sent telnet (or SSH) commands. Vary simple ones like "1" or "a" to trigger the device to flash lights or move around. It will also need to retrieve line from IRC when someone says my name, it will displayed the line that has my name in it. What is the best way to do this w/o Ethernet cord?
thanks,
Mariah

If you want a wireless connection between the Arduino and the PC, there are a number of ways to do this.
XBee is a wireless solution for mainly robust serial communications; if serial communications are what you need, then it is one way (although expensive) to do it. If you need a less expensive option, look into "virtual wire" serial RF modules (they come in different frequency flavors depending on the country you are using them in - so get the ones proper for your country). These modules are very simple to interface (though coding for them can be a pain). Note that on the PC end of things, you will need an RS-232 level shifting converter, or you can use an FTDI cable or interface to get you the TTL serial levels you need.
The only other option - if you need wireless TCP/IP connectivity - is to use an 802.11 wifi interface (module or shield) - these aren't cheap either...
Oh - there is one other option (if you can live with a 10 meter distance from the PC) - bluetooth. There exist modules and shields you can use to do serial bluetooth communications between the Arduino and the PC.
Something to keep in mind about all of this (because you have asked about this, about wav/mp3 playback, and about motor control): You can only fit so much code on a standard Arduino, and some of these items (like combining an MP3 playback shield with an 802.11 wifi shield) may take up a lot of code and SRAM space on a regular Arduino. You may want to research this as well (or you could find you have a bunch of parts and no way to code for all of them). Also - you need to check pin compatibility, to make sure none of the shield share any signaling I/O pins so they don't conflict (or that they have ways to change this on-board - else you'll have some hacking to do).
Again - good luck - and don't get in over your head!
Hey,
I was hoping to keep the pc out of it, and connect it straight to the internet, I'm also trying to stay away from rebuilt shields for that exact reason. I have 6 digital pens free and all the analogs free. Thanks for your input. I like wifi and gsm honestly. Anymore input would be awesome!
thanks,
