Integrating the bag alarm system

Investigate and apply methods to attach the bag alarm device to a piece of clothing

This is one of a series of resources to support the use of the BBC micro:bit in Design and Technology lessons.

Schools are busy environments and it is easy for learner’s bags to be left unattended, taken by mistake or even stolen. Alarm systems using embedded electronics and programmable components can be developed to protect the property of learners during the school day.

In this unit of learning, learners will research, program and develop a working school bag alarm system using the BBC micro:bit.

Activity info, teachers' notes and curriculum links

In this activity, learners will design a fully integrated product. They will investigate and apply methods to attach their device to a piece of clothing.

The activity sheet includes teachers' notes, useful web links, and links (where appropriate) to the national curriculum in each of the four devolved nations; England, Northern Ireland, Scotland and Wales.

Remember, it's all free!...and registration is free too!

All activity sheets and supporting resources are free to download, and all the documents are fully editable, so you can tailor them to your students' and your schools' needs.
