What it does
It uses the accelerometer to guide you through the process of doing CPR. We want it so that you could simply put the phone on top of the chest or beside your hands, and the phone will prompt you when to apply pressure and how many times per minute, and how much pressure to apply.
How we built it
We are using the arduino's accelerometer to learn about reading raw values of the accelerometer and trying to make an accurate algorithm for applying pressure that is required for CPR. Meanwhile, the app will guide users through visual illustrations and will eventually integrate the accelerometer so that the phone's accelerometer will be used instead of a separate Arduino sensor.
Challenges we ran into
Processing raw accelerometer values are pretty hard to do.
