I seem to spend way too many hours at my desk each day so I wanted a way to count how many hours I spend at my desk in a year, just out of curiosity. My plan is to have a button when I sit down which continues the count and another button which pauses the count when I get up, therefore its only counting time when I am at my desk. I would also like an LCD screen which shows the seconds, minutes and hours as its counting, although i'd like to be able to turn this LCD on and off with a toggle switch.
So the difficult things i'm coming across is counting the time in hours, minutes and seconds as well as how to store the count variable when the Arduino is off. I've also never used a LCD display before although I conveniently own a 128x128 pixel colour LCD display by Duinotech.
If I was to take the project further, eventually I would like to make the screen show how many hours I've been at my desk total, during the year, during the week and that day. So the LCD would have four separate timers counting up.
