Do a search on the Internet for an Arduino ADC that is packaged as a shield (and that you can buyabout $15-$30) and is advertised as being better than the built-in one. You will get lots of results back, and many will not be shields. You will have to click on a few of the links to find what we are looking for. They are out there, so in this sense, there will be several correct answers for this assignment. You are on your honor to do your own research but you may compare your results with a classmates research.

I am unsure what I am looking for and could use an example with a link.
