Design a home security system
Use the BBC micro:bit programmable system to create a working prototype
This is one of a series of resources to support the use of the BBC micro:bit in Design and Technology lessons.
Home security is increasingly important as homeowners look to ensure that their properties and possessions are protected from potential burglary. Alarm systems are being developed with increasingly complex embedded electronics and programmable components.
In this unit of learning, learners will research, program and develop a working door access and alarm system using the BBC micro:bit.
