1  Products / Arduino Due / Due and Xbee on: December 15, 2012, 12:52:43 pm

Has anyone tested the Due with a xbee module (Series 1 or 2) for a connection to another arduino?

Till now, I found just one shield thats described as running with the due:

And the question is, if i need a shield for the xbee module running on the due. Or are they just for levelshifting because the xbee module is running at 3,3V and the other arduinos except the due are running with 5V? Hence the due is running with 3,3V like the xbees, maybe i just have to connect them to each other? And if, how should they be connected?

Thanks for the infos! Maybe you can tell something about your experiences when you tested yours :-)

My due hasn't arrive today. I've to wait till monday  smiley-cry

tomorrow my Due should arrive (If i can trust the shipment tracking) :-)

I want to control about 20 Servos with the Due. I read the topics about servo control here in the Due forum, and there should be a working library, if i understand that correct. But what i didn't found was a concret answer about the "3,3V problem".

For 20 Servos it is clear, that i have to use an external power supply, especially because i want to use very strong servos. The red plus und black minus wire of the servos will go to a lipo accu. I want to use lipo servos running at about 7,4V.

But can i directly connect the yellow wire to the Due or will it damage it? If it does, what can i do against that?

Thanks very much! I'm sure, I will have questions :-)

Thanks for your help!

Now i konw, that it is possible with arduinos, hence I can start the project :-)

I go with simple codes first, just so I know it works, then I make them more complex but also more efficient.

Off course i will start with short steps. First step: Get an arduino due. All shops have them in backorder :-(

Nice vehicle! So it seems to work :-)

But can you tell something about the delay? Do you see a big delay between touching the screen and the moovement of the vehicle?

I'm new here at this forum and i'm new using arduino (and sorry, my english is bad  smiley-red). But I'm not totally new at programming and using microcontrollers. We made many projects at the university with microcontrolers, but thats been a while and now I'm only programming C++ and Java for Linux. So thats the reason why I thought the arduino could be a perfekt system. Many tutorials and a big comunity where maybe I can get help :-)

What I want to try is to build a rc transmitter and receiver on my own. I thought about taking an arduino due in a model as the receiver and a due in the transmitter together with wireless shields and xbee modules. But I want to do many things with the rc system. I want about 15 - 20 servos and about 10 sensors (temperature and so on) in the model. The sensor data should be transmitted to the transmitter. I know, now the receiver is also a transmitter and the transmitter is a receiver. Just say, receiver is in the model, transmitter is in my hands :-)
On the transmitter i want two 3 axis joysticks and maybe a third one. With 12 analog inputs on the due this should be makeable. And on the transmitter the sensor data from the receiver should be displayed, how exactly is not important. And maybe some switches on the transmitter. An important feature is, that the delay between my inputs and the reaktion of the servos is not too big, otherwise it's not that funny driving a modelcar.

Now, my question is not "How can i do that", it's more "Is it possible with arduino to do that"? I know, if it's possible, it's a long long way and much work, but thats no problem. I have a normal rc transmitter for driving my models, so i have no stress to get it working. I want to learn, so the way is the goal ;-)

What do you think, is it possible to realise my project?

Kind regards from Austria, Heinz.

PS: I don't want to make a transmitter for an model airplane or heli or something dangerous. I want it for slow cars that are not driving far away from me. If it's working 10m stable, it's enough.
