Sensors

Some sensors to make. A lot of the ideas I want to try require different kinds of sensors, so I figured I just collect all of them in one place.

For the record, this list is more for me being able to not have to search through 700+ Favorites to find the specific project I'm looking for. As I cull through my Favorites, this list will grow. Once I've gone through all of the Favorites, I'll start paring these lists down by finding the best of the various similar projects.

Hopefully, though not the original intention, these lists can help other people who have gone searching for Instructables and gotten lost in the maze.
