Making a Room Alarm
One of the things we love about the micro:bit is how easy it is to attach other components like speakers and switches. We created this room alarm project to solve a simple problem, two curious daughters that are always "borrowing" Dads things without asking. We learnt how to wire up external components, make a simple switch from aluminium foil and how to make really annoying sounds from the micro:bit.
