Korman, I have configure my unsed pins, as OUTPUTS and they still have a costant voltage of about 3.5 v. So I think, definetly, that I have fried part of my arduino´s micro.

Of course crosh, obiously I will buy another one to continue my work, but as you Know, the time is gold, and buy another chip will waste at least one week, that´s why I have asked in this forum.
However, thanks for your answer, and if you have any new idea don´t doubt in share it with us.

Thanks for your answer Korman.

I completly agree with you, is possible that I have fried only some parts of my Arduino, because I have just check the digital pins I´ve notice that some of these pins still works.

Nevertheless, I haven´t configure these pins as nothing in the setup part, so if I configure these pins as OUTPUTS, should these pins floats?

Hi, I´m doing a university project with arduino. The device controls the speed and the position of a motor with the PWM pins. My problem is that most of my digital pins have a constant voltage, when its should be a 0v, because I don´t use these pins in my program.

And I have notice that my arduino (only the chip ATMega 328) is too hot, so I though that I had fried my arduino, but I can load some programs like the blink led, and it works, but I still have mos t of my digital pin with a constant voltage.
Can somebody help me?

I have been looking for what is exactly a point to point network for regard if is posible to me do what I told in my first post.
I have found a very complete description of this and of course of the rest of the possibles networks configuration.
I left it here the for who wants have a look.

Thanks

Lots of thanks Paul S

I think, that it is posible, I have seem some examples in some forums, in my opinion the network should have an esay behaviour (just setting up the parameters MY, BD, AND DL):

1s en device ---2nd end device---gateway(again to the 1s end device)
      

But I will have a look to data sheet to test what you have told me.
In other way, I configured the xbee modules with the x ctu, and i just change the parameters that I write on my last message.
I will show you the code, It can be useful, maybe you could understand better what I want to do
 THANKS

Hi, I'm doing an arduino proyect with 3 arduinos duemilanove and 3 xbee shields  serie 1 (1 is going to work as a gateway and 2 as an end devices). The object is make a regulaltion feedback, where the gateway is use to monitorize the process and to set up the proces's control(for example set up the constants of PID). I can communicate the 1st end device (actuator) with the 2nd end device(sensor), and the 2nd end device with the gateway, but I can´t  send constants beetwen the gateway and the 1st end device, and I have configurated the xbee modules correctly, as is shown is many forums, webs, and tutorials (setting MY, DH,DL,CH.PANID, etc).

Can anybody help me to know how I can avoid this problem?

Regards
