 # Description
-This algorithm is derived from the Brainflow SpO2 algorithm, and uses PPG-R and PPG-IR data from the EmotiBit to calculate SPO2 level. 
-The repository has been setup to enable using the spO2 source code in both, Arduino and a standalone python script. We did this to enable testing source in pyhton, to fast track testing and enable us to improve algorithm performance with a shorter loop.

 - Arduino: To use this library in Arduino, just clone the git repo or download it using the Arduino Library manager into your `Arduino/libraries` directory.
 - Python:
-  - We use pybind11 to create bindgings for the c-source. The resulting `pyd` file is then used by the python script.
-  - To learn more about using pybind and pythin, check out the [pybind/README.md](./pybind/README.md).
