Electrical Engineering Projects
Santa ornaments that talk, motion alarms, amplified crystal radios and more! These electrical engineering projects are perfect for engineering students and more advanced makers.
While an adult’s help is needed, our projects are particularly fun for kids to help out with.
These breadboard projects include step-by-step instructions. We also describe how the electrical parts function to make these circuits work.
We’ll tell you what supplies you’ll need and we’ll embed some helpful (and fun!) videos to get you engineering in minutes.
You might also wish to take a look at all of our cool engineering projects or just our beginner-friendly basic electrical circuit projects
We also have a helpful basic electronics page that teaches skills such as how to use a breadboard and multimeter.
