Carnegie Mellon Robotics Academy: Electrical Foundations

Master the Basics of Electricity and Circuitry One Session at a Time!

This course provides a hands-on introduction to the foundational concepts of electricity and circuitry. Using Arduino as the core microcontroller, students will learn how to work with circuits, control signals, and integrate sensors. By the end of the program, participants will construct an e-panel, a system containing all the components of a typical robotic system, providing practical experience applicable to robotics and engineering projects.

The course is project-based, allowing students to focus on hands-on learning. For students who watch the videos at home, come prepared to class, and complete the projects on time, the course can be completed in as little as 3–4 months with a commitment of 1.5 hours per week in class. To earn a certificate, students must complete the projects according to the given specifications, which will be reviewed and approved by instructors before being uploaded. Additionally, students must pass the final exam with a score of 70% or better to complete the course and earn their certification successfully. The cost for the certification is an additional $200.

Developed by Carnegie Mellon Robotics Academy

This course was developed by the Carnegie Mellon Robotics Academy (CMRA), a global leader in robotics education. CMRA researches how educators can use robots to teach Computer Science, Science, Technology, Engineering, and Mathematics (CS-STEM). Their mission is to create CS-STEM opportunities for all learners by designing research-based, classroom-tested solutions to foreground essential STEM concepts.
