Question about controlling your arduino

Is it possible to control your arduino from rc controller to xBee module. Rather than having it arduino to arduino?

from rc controller to xBee module

You will need to explain in more detail what you wish to do.

What sort of RC controller?
What is intended to go to the xBee module?
What will be between the RC receiver and the xBee module?

An Arduino can certainly interpret the pulses from an RC receiver that would normally control servos. However that is hard work for an Arduino compared to receiving wireless data with an nRF24L01+ transceiver or an xBee.

...R

For instance, I have a 27MH rc car controller with basic analog sticks, and i'd like to be able to control servos that are on the Arduino robot for example. The nRF24L01 seems great, but I don't want to have to use 2 Arduino's to control 1. I'd like to use that controller by itself for example to send commands to the Arduino.

Thanks!

What people normally do is use both the RC transmitter AND RC receiver.

Then, instead of wiring the outputs of the receiver directly to the motor/servos, the outputs are wired to digital input pins on an Arduino. Using the pulsin() function, the duty cycle of the PWM wave is obtained, extra processing for servo/motor commands happens in your Arduino sketch, and then the new motor/servo commands are then sent out.

What exactly are you trying to do with this project?
