Tinker Thoughts
This project is just for fun, really. It is easy and affordable to just get an Uno R3. However, going through this project will help with soldering skills as well as test your patience when trying to neatly route all these jumper wires. It's fun nonetheless! At the end of the project, you'll get a Nano that has the footprint of an Uno. It works with all the standard Uno Shields (shown later), and we've even added a reset button, although not at the same location.
