We are trying to get two arduino unos to communicate to each other using xbee shields. We tried using the tutorial but we could not get the devices to work. This is our first arduino project and we don’t know what to do. Please help.
What we have here is a failure to communicate.
We will need a bit more information. Where in the example did you run into problems?
Did it not power up?
Did it not compile?
Did it not upload?
Did it open a portal to another Universe?
Kinda of hard to help when we don't know where you got stuck.
Try each part in turn by itself.
After loading the Physical Pixel sketch can you turn the LED on and off when you type H and L?
On the second unit does it spit out H and L once a second?
Did you move the jumpers on the shield?
In addition, tell us which XBees (by posting a link to the manufacturer's site, for the ones you actually have, not a link to an expired e-bay seller) and which XBee shields you have.
Tell us how you have configured them. You did configure them, didn't you? The note on the digi site that says that they communicate right out of the box is pure, unadulterated BS.
We tried using the tutorial
There's only one tutorial? Which one did you try to follow? Was it the right one for the hardware you actually have?
