Do you struggle to get a good sleep at night? With this unique project from flyingpudding you can use an Arduino to build your own sleep tracker. The tracker allows you to monitor your sleep cycle and the movements you make during the night. The tracker is quite simple and is based off three accelerometers which record changes in your sleeping position throughout the night.
The Arduino sends the movement data to a laptop running Python which produces a very informative sleep pattern graph. You can see an example of the kind of data that this tracker produces in the picture below. If you want to get started making your own sleep tracker checkout the following link.
