ArduPi-ECG

• toolkit for full HRV (heart rate variability) analysis of Pulse Sensor data using standard (Linear Regression, Fourier Extrapolation) compared to groundbreaking new techniques (Wavelet transforms, Chaotic Analysis, Neural Networks)
• script for real-time python display of bpm data from Arduino Pulse Sensor, on Arduino Uno, using Matplotlib.

Requirements: Arduino Uno/Arduino IDE or Raspberry Pi, Python 3, Matplotlib, Numpy, PySerial, Arduino Pulse Sensor

TODO:

• Use NN regression on regressive output from real data (either standard or NN LR) ...?
• Use ALL models on real data
• Build Chaotic model
• Build DeepNNs
