A few months back I bought a BBC Micro:bit at the Science Centre in Glasgow and it's been fun building apps with the single board device. I thought I'd write a blog entry about the latest project which will be a more permanent installation in our bathroom. A toothbrush timer! Kitronik sell an add on board which provides power from a coin cell battery and a piezo buzzer called a Mi:power, they also sell a Mi:power case which is designed to fit around a Micro:bit fitted with the Mi:power. This assembly combined with some code offers a neat toothbrushing timer. By using the display on the front we provide a short countdown - with a little tune through the buzzer. The program show 6 areas of the mouth to brush each for 20 seconds before showing a toothy grin and a finishing tune. Each time the area of the mouth changes it plays a 'level up' style jingle.

My personal blog about stuff that happens which I can't fit on twitter or when I want to keep a diary.
