Hi guys,
I am currently using an arduino uno for a project which contains two buttons and a servo (one button moves the servo to the right and the other one to the left)
I was wondering if there is a way to control the servo wirelessly and searched online a bit but the only way I found was with a transmiter and reciver using a second arduino, and my question is- can I control the servo without a second arduino?
(distance of about 1.5m)
thanks, Shak0706
I don't see any practical way to avoid having the Arduino at the servo side of the RF link. I suppose you might be able to replace it with a dedicated servo controller and use some sort of bluetooth or similar connection to send commands to it, but that strikes me as even more complex and expensive than the Arduino based solution.
If you adopt a standard wireless communication mechanism such as WiFi, Bluetooth or XBee which can be used by a PC then you could potentially eliminate the Arduino at the sending side if your transceiver is one that a PC can connect to directly. Given the minimal cost of an Arduino clone, I wouldn't have thought there was any strong incentive to eliminate the second Arduino, but it ought to be possible if you want to - you could easily end up making your solution more complex or expensive in order to achieve that, though.
If you can find a simple tx/rx pair that can send/receive basic hi/lo signals, then you might be able to drive the pair just using the arduino servo PWM output.

I think that doing the real-time servo signal transmission via RF would be lead to an extremely difficult solution, because latency and jitter over the wireless link is inevitable. It would IMO be far more sensible to transfer to position command over the wireless link, and have a device local to the servo generate the required real-time signal.
You can use this wireless remote switch replace your two buttons
So you can use one arduino uno at the servo side.
I am a beginner to Arduino programming and especially Xbee, and am working on a similar project. I would like to control a servo with a potentiometer wirelessly. Is this possible with one Arduino and an Xbee pair? Thanks in advance.
