Microcontroller Projects Ideas

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.
