I discovered the Arduino world about one week ago, with the intention of making RC stuff. As a beginner, my goal right now is to achieve this very simple thing : wirelessly controlling a servo motor with a potentiometer (a RC version of the "Knob example", in other words). I have a few questions about this :
What hardware do i need for this ? Something like 2*(Arduino Uno + Wireless shield + Xbee transmitter) ?
In addition of the official Wireless shield, i saw there was an Xbee shield. What is the difference between them and which one is the most suited for RC model control ?
Why not just use existing RC Equipment which already comes in a nice robust box with easy to use controls and then interface that to your Arduino to do whatever clever stuff it is that you have in mind ?
Heres one of many examples from my blog -
and here is a series of posts that shows you how to do it -
Thank you for the links, your blog looks very complete. It is nice to know there's someone i can question if things go bad.
But for this project, which is actually an airplane equipped with a webcam (and some other sensors) that will send information in real time to my computer, i think i will have to use the wifi technology anyway, hence my first questions.
Use the existing technologies for what they are good at, you can get very inexpensive multi channel RC Control systems ready packaged for flight, then use a separate link - wifi or whatever you choose - for data.
Thats the way I would do it anyway.
No idea if this is any good, so its not a recommendation, but for 30 dollars you get six channels ready to go and then can concentrate on the more interesting parts of your project -
