In Exercise 10 we were able to combine the modules and knowledge we acquired in Exercises 8 and 9 to build a radio receiver. We already have a transmitter from Exercise 8 so in theory we have everything we need to build a complete wireless data link. However, if we tried to build one out of what we have, we would run into a number of problems:
This means that if we want to add wireless communication to our repertoire, we will either need to do a lot more work, or take the easy way out and let someone else put everything on a single chip then just buy one. Since the end of the semester is rapidly approaching, the second alternative seems the best choice.
