Early exposure to embedded computing systems is crucial for students to be prepared for the embedded computing demands of today's world. However, exposure to systems knowledge often comes too late in the curriculum to stimulate students' interests and to provide a meaningful difference in how they direct their choice of electives for future education and careers. This paper describes an experience with integrating embedded computing systems education into high school and early undergraduate curricula to give students that needed early exposure. It provides assessment data that illustrates the success and limitations of the efforts described as well as the lessons they hold for a reform of the undergraduate curriculum and its impact on high school education.
