Working on programming the LED strip to visually communicate the heart rate and activity of the user. The example file that you can download from pulse sensor's website utilizes an interrupt that determines a BPM variable. Using this variable we can change the rate of blinking. By setting an average control heart rate we can shift the colors to visualize activity.
