We aim to understand the potential applications of BBC micro:bit as a programmable IoT platform for children in order to anticipate a range of scenarios which may present different challenges in terms of privacy and security. We will look to identify current barriers to being able to responsibly deploy micro:bit as an IoT tool for children in order to develop a comprehensive understanding of the potential implications of use of this and similar tools for which design solutions are needed. We will then aim to develop a list of recommended programming components for the micro:bit to make it acceptable for child users in order to responsibly deploy micro:bit and similar programmable IoT tools for children.
