Optical Heart Rate Detection (PBA Algorithm) using the MAX30105 Breakout
By: Nathan Seidle @ SparkFun Electronics
Date: October 2nd, 2016
https://github.com/sparkfun/MAX30105_Breakout
This is a demo to show the reading of heart rate or beats per minute (BPM) using
a Penpheral Beat Amplitude (PBA) algorithm.
It is best to attach the sensor to your finger using a rubber band or other tightening

Created March 20, 2016 02:46 — forked from shaunlebron/angleLerp.js
The best way to interpolate 2D angles
/*
2D Angle Interpolation (shortest distance)
Parameters:
a0 = start angle
a1 = end angle
t = interpolation factor (0.0=start, 1.0=end)
Benefits:
1. Angles do NOT need to be normalized.
