MATLABArduino.org and its associated YouTube channel were created to provide free-of-cost, high-definition YouTube videos that demonstrate the use of two powerful technologies - MATLAB and Arduino - to perform data-driven, embedded systems tasks for embedded systems education. This initiative aims to broaden the participation of students in engineering through the use of low-cost hardware, real-time visualizations of otherwise abstract concepts, and easy-to-follow instructional videos. This paper describes the video content developed as part of this educational initiative in detail. Viewership trends of the YouTube channel are reported to describe insights about the video engagement and viewer demographics. A qualitative analysis of the YouTube comments left by the viewers is provided, along with highlighted comments that show recurring themes. Finally, challenges encountered in operating this website and YouTube channel in the context of remote online education for embedded systems are described. As physical computing-based online education becomes increasingly pervasive, we anticipate that open educational resources similar to MATLABArduino.org will drive a significant amount of learning for engineering students. The insights presented here may guide current and future open educational initiatives for embedded systems remote learning.
