I want to control a servo wirelessly with a potentiometer for a project i'm doing, but don't wanna spend the money on the Xbee. It doens't have to involve the arduino, but I would like for it to. Any help? I've been looking and can't find anything. I could use a IR sensor to do so, but I need to signal to be picked up even when there is an object in the way.
Bluetooth is an option. I have a WD-05 based chip that I've hooked up to my 3.3volt Teensy 3.0. I believe it should be safe to use on a 5v device like an Arduino as well. I've paired it with my Android smartphone and I have sent messages via text streams back and forth: http://www.ebay.com/itm/HC-05-Bluetooth-Transceiver-Host-Slave-Master-Module-Wireless-Serial-6pin-/221158958927?pt=LH_DefaultDomain_0&hash=item337e19e74f
For the Arduino, I got the bluetooth shield that was made by Seeed. I bought it from Radio Shack, but it is no longer in their catalog, but if you live in the USA, perhaps your local store still has stock that might be on sale: http://www.seeedstudio.com/depot/bluetooth-shield-p-866.html?cPath=132_134
Another option is RadioBlock. Unlike bluetooth, which is a 1-1 connection, RadioBlock offers a mesh network, so if you have a bunch of devices, each can communicate. In addition, the mesh can route packets to allow for remote ends to communicate via intermediate units. I bought this during the original kickstarter campaign, and I just got my two units, but I haven't done anything with them yet: http://www.coloradomicrodevices.com/the-radio-block/
Another option is OpenSource RF. I looked at them during the kickstarter campaign, but at the time, I did not have the money to buy a set. I suspect these are out of your price range, but if you need to communicate with things far away, this might be the ticket. http://www.opensourcerf.com/
A cheap solution:
I have used a cheap set of 433 TX/RX like these:
As transmitter I used an Attiny85 with a potmeter and manchester encoding.
For receiver and servo controller I used Arduino Uno.
It works, but don't expect long range, maybe 5 - 10 meter

An inexpensive alternative.
What I'm mainly looking for is a small stand alone way to send values from a potentiometer to a servo WITHOUT it being hooked up to a smart phone or a laptops. Maybe like a transmitter or a receiver kind of setup. I want the end product to resemble this...
But with no wires between the servo and the potentiometer. Does anyone maybe know of a small transmitter and receiver that would work for this project?

A cheap R/C rig?
What range do you need.
Maybe a cheap toy car, or other rc toy
I'm looking for control up to or greater than 20 feet. I would prefer to use a micro controller that I can hookup the potentiometer to simply because I don't wanna dismantle a controller and try to make it fit my project box. Does anyone know of a small transmitter and receiver pair with a good video or instruction manual on how to hook them up for servo control?

I mentioned the 433 MHX rx/tx earlier, another option:
or maybe bluetooth
Hi everyone! kinda new here first post.. :D
I read this older forum but the answer to the question was not answered.. Im trying to do the same.
I want to control a digital servo that i have with a potentiometer using the arduino bluetooth serial wireless port module.. this means WITHOUT a smartphone!! with a potentiometer! I have what i believe is the bluetooth wireless port module sender and receiver, arduino uno, but i have no idea what to do to make this work. I dont have an xbee! and iv heard i dont need one to make this work. Im also looking for a short distance 2 meters is fine.. Any help or guidance on this is highly appreciated! Thank you :)
