Sit Bit
Heartbeat break reminder
A desk object that reads your heartbeat and reminds you to take a break.
Overview
Sit Bit is a small heart that lives on your desk and beats with light. It keeps track of how long you have been sitting and reminds you to stand up and move around.
It is built with an Arduino and its onboard sensors. When you have been in the chair too long, the heart starts pulsing to catch your eye, and it settles down after you take your break. It can even tell when you try to cheat the exercise.
