2 arduino slave sender, master receiver help

I have found the basic arduino tutorial for this, but i am wondering on how to do this with pushbuttons. I want to have a slave 50 feet away or so, not biggie, but it will have a certain number of PB's lets say 4 for instance.

Is there any examples anywhere of taking a slave arduino and PB's, and monitoring the PB's and sending the status to the master. Which in turn uses those inputs for various functions. I cant find any examples of how to do this, I've just found the tuts that send characters back and forth and print them.


Using I2C you can have one master Arduino and multiple slaves. start here - http://www.arduino.cc/en/Tutorial/MasterReader
