Build Instructions & Materials

Step-by-step build notes and a simple parts list so you always know exactly what to do and which components to use.

Circuit Diagrams

Clear, easy-to-read wiring diagrams that show you exactly how to connect each component.

Code

Ready-to-use Arduino code you can upload directly. Each project includes clean, well-commented examples that help students learn by experimenting and modifying real code.

About the course

The Free Project Library is a collection of simple, hands-on electronics and coding projects you can build using the Horizon Uno and the components in your kit. Each project is designed to be clear, approachable, and fun—even if you’re brand new to electronics. Inside, you’ll find downloadable code, circuit diagrams, and quick build instructions to help you learn by doing. Whether you’re a homeschool parent looking for easy STEM activities or a student who wants to explore engineering at your own pace, these projects make it effortless to start building cool things right away. New mini-projects are added regularly as we release more builds on Instagram, giving you fresh ideas and endless opportunities to practice, experiment, and create.

Cristobal Rincon Rogers

I'm a robotics engineer, educator, and the founder of Horizon Robotics Lab. I’ve spent years building robots, studying engineering, and teaching students who never thought they could understand electronics. My journey started with curiosity and a lot of trial and error. I didn’t grow up knowing how to build circuits—I learned by breaking things, fixing them, and slowly building confidence through hands-on projects. My goal is to to make engineering feel simple, fun, and accessible for everyone, especially students who don’t know where to begin. I’m passionate about helping kids and families discover the joy of building real, working electronics. My goal as a teacher is to remove the intimidation from STEM and replace it with creativity, exploration, and that feeling of, “Wow… I built this.”
