Design an alarm for a schoolbag
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.
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 develop their programmable system using the BBC micro:bit and the device’s inbuilt accelerometer to detect movement.
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.
Download the free activity sheet below!
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.
And please do share your classroom learning highlights with us @IETeducation
