If I want to buy these separately, what exactly do I need?  Could you give me the links to buy them?(on Farnell or Radionics) Thank you very much!

 Here is a video show how to use the Xbee in this case with 2 Aruinos. http://www.element14.com/community/videos/1910


Here is the video index that would be good for the beginner. http://www.element14.com/community/groups/arduino

Thanks for your help, http://radionics.rs-online.com/web/p/zigbee-ieee-802154/0436389/ Can this fulfil my requirement as I can't order on sparkfun. (can only on Farnell and Radionics)

Hi everyone,

I am testing the LDR recently, but I have no breadboard,(I found most project with LDR is done through a breadboard).

My question is, can I connect my LDR directly to my arduino, and to control the LED on my arduino (13)?  If it can, how to connect?

Thank you.

Thank you very much, I have ordered one.

When you want a board that plugs directly into an Arduino the term used is "shield".  A search for  'Arduino xbee shield' should turn up all sorts of possibilities.

If you don't need it to plug directly into an Arduino but want the essential support circuitry and an easy way to connect to the signals the term used is "breakout board".  A search for 'xbee breakout board' should turn up plenty of choices.

Thanks for your advise, I need one to connect to the arduino and another to the PC,so that I can communicate the arduino with the PC wirelessly by using xbees. Sorry I'm a newbie and could you tell me which type I need?

Hi everyone,
I want to make a project that control a robot wirelessly, and I decide to use xbees.
But I never use it before, it seems xbee can't directly embedded on an arduino, do I need some adapter or breadboard or something like that?

Can someone tell me what exactly I need  and give me the link to buy them?

Many thanks.

Well ask your teacher...
The Romeo is just an Arduino with an H-bridge, some buttons and extra headers added, so why another Arduino only your teacher knows.

Thanks, then could you tell me which will be more suitable to control a robot?

Hello pros,
I'm a quite noob and I get two arduino boards from my teacher, but I think Romeo will be enough to control a robot, what is the Duemilanove used for?

Thanks.

Some links of a similar subject, with the bottom web cam showing basic web control.

Thanks for the links. But I still feel confused about the implemation process.
To achieve my goal, I want to create the web interface(for the client to control and monitor), the web server .
Could you tell me how can the web interface control the robot? Is it to communicate with the web server or the Arduino server? How?

Hi guys,
I want to build a program to remotely control and monitor by a 4wd mobile robot which has a network camera placed on it. My idea is like this:
I create a java client side on the remote computer(anywhere in the world), and the java server in a local computer, which has the same network as the arduino. The local computer is communicated with the arduino, in order to control the robot and camera, the camera gets the image and send back to server, then the server send to remote client.

So that even I am in China, I can control the robot which is in dublin.

I have a few questions about this.
1.I think in this situation, wifly shield may be more suitable to complish wireless control, can somebody recommend one wifi shield  for me?

2.Can Arduino programming language communicate with java? How can I control it using java IDE?

Thank you~

Does it have to be over the Internet?

Yes, my project's purpose is: even I am out, in a cafe or at school(where I can get internet), I can remotely control the robot at home over internet. Can this be done with wifi shield?

Only the two wifi shields can connect directly to the internet. Xbees can only connect to other xbees, so you would need an xbee connected to a computer for that to work.

It seems wifi will be more suitable for me, so if I want to use xbees, I have to connect one to the arduino and another to the pc, right?

Hi everyone,
I want to remotely control a robot over internet with Arduino, I have done many research and found that all of these three  boards can accomplish wirelessly control.

Can anybody tell me the difference between them and give me some advice about which to choose?

Thank you very much!

If someone can compare them in detail, I will be appreciate.

Hi guys,
I want to make this project wireless, and I'm considering to use a Xbee, I don't know which type will be the best, can anyone send me a link to order a Xbee for this project?

Hi everyone,
I want to control a robot over internet remotely and wireless. Now I have a Ethernet shield. But it seems to be wirely, is there any equipment that can be wireless controlling the robot?

 I know Xbee can do that, is there anything better ?  Could you give me some link to the shields which may be appropriate in this case?
