In addition, I would reccomend an ATtiny in conjunction with these transceivers. That's the cheapest method I'm found so far for low cost two way communication.

I am not sure how to hook these up to a small arduino like arduino nano or arduino mini...I am guessing I put one of these RF transeivers on the arduino connected to my laptop as well...Once I do this will it be okay if I have 5-10 small arduinos sending POT data to the laptop arduino?
