Summer programs are the latest trend in extracurricular STEM education programs offered by universities. Efforts are made towards residential summer programs, which have the ability to expose students not only to specially designed STEM activities but to the university campus environment and student life, as well. These types of programs are expected to have better success in getting students engaged and to capture their interest in STEM fields. This paper presents one example of designing and implementing a summer residential workshop in order to expose high school students to the field of engineering technology, specifically to electrical circuits, electrical prototyping, microprocessor based design, sensing and measuring the environment, and the Internet of Things. The camp includes other workshops that are focusing on other areas of STEM, specifically science and mathematics. The paper presents the workshop setting, the activities organized, and the feedback received from students
