I'd like to control an electric engine with an Arduino with the wireless communication. I heard about the Arduino Fio, but I can't understand how I should sent to it the wireless signals to tell him what to do.
Can you help me?
If you know some others Arduino that can comunicate with wireless signals pls let me know.
Thx all!
Range?
I think something like 20-50mt should be fine
no one has got some ideas? =(
I'm sorry I should have explained my project better. I should build a quadricopter (something like this iPad pilots the AR.Drone - YouTube , obviously less complex). The arduino should manage the 4 engines and receive some segnals from a pc (I don't know which wireless tecnology should work better) to change the speed of those engines in order to make it move. I don't even know if there is an arduino that can receive segnals and manage 4 motors. I have found this Arduino Fio that can be programmed with the wireless technology, but I don't know if it is also possible to give him commands in that way.
In your opinion what arduino should work better? and what wireless technology should is the best for this application?
Most seem to like the Xbee system, which is basically like a transparent wireless serial connection in most ways.. you can treat it as if the arduino is physically connected.
Controlling four motors (speed wise, I am assuming) is easy enough, you would use PWM output, and a power transistor. Arduino would support 255 levels of speed control, from 0-100% of power. Arduino can support PWM via extra software for up to fourteen channels (I think), but the "native" arduino has more than the four you would need. Look in the "playground" section of the reference, it gives some good examples as well as some pointers as to where you can find information in more detail.
Thank you very much, the Xbee seems to be what I was looking for. I hope that the battery of the Arduino can keep engines running for long enough.
