This section is all about giving you
ideas for projects to implement using microcontrollers. These projects
typically do not contain microcontrollers as they are based on projects from
several years ago.
Even though they are older designs (created by some of the best minds in history), the ideas they contain are still useful. You can use the information here to create your own projects using a microcontroller to make the system easier or you can just build them as they are described.
