This is a magnetic door contact ¹, I've connected one to the Arduino and written some code so that it will send me a text when the door it's on is opened or closed. Now I just need to come up with some practical applications for this... I'm thinking so far:

monitor the bin shed door (let me know if the postman left a parcel there)
monitor the beer fridge, build up a pattern of when it is opened and closed and so when it really needs to be powered up
let me know when the tv / hifi cupboard has been opened, so I have a better idea why the tv stopped working...
security monitor on the shed door
let me know if Clare has left the fire doors propped open again Any other practical application suggestions appreciated.

arduino: Microcontroller, hardware prototyping platform, a tiny specialised computer.
