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.
Thanks,
J
