In this paper we present the concept of re-usable educational bricks for the teaching of digital ethics. After describing the motivation behind the concept, we provide an overview of a standard template that can be used in the design of such a brick. We then briefly review the bricks that are at different stages of development, evaluation, and deployment, following this template. Finally, we conclude with a more detailed review of the development of a brick based on a case study which examines the use of "electronic pills" (e-pills) in the health industry. This case study falls within the computing topic of the Internet-of-things (IoT), and focuses on the ethical issues related to security and privacy.
