“Here’s my mood gauge. It started out as a ‘I know what we need…’ discussion in the office, but since making it I think it could also function as a child behaviour monitor for parents or a RAG/traffic light gauge for teachers - albeit an elaborate one. Quite simply, as illustrated by the animated gif above, you push a button to display the corresponding mood - so everyone who’s looking will know what mood you’re in (and will know to tread carefully if it’s showing red). Additionally I’ve added a clock function as there were enough pins left over on the Arduino to do so. In-keeping with the ‘mood’ theme of this project I decided to the clock should show a ‘mood’ depending on what day of the week it is - obviously Monday is bad and Weekends are good!”
