Heart Monitor
A reinvented heart rate monitor that uses light bulbs to represent one’s pulse.
The Heart Monitor is a reinvented heart rate monitor that senses one’s heart rate through a pulse sensor and simultaneously displays it through light bulbs. The viewer approaches the monitor and presses a finger on the sensor and can view his or her heart beat instantly. The Heart Monitor uses an arduino, a pulse sensor, a light bulb, light bulb socket, along with a relay, and wires. The hollow computer monitor, solitary light bulb and dirt impart a stark simplicity to that most complex of subject, the human heart.

Hollowing out the Screen
classmatessssss working hard!
Deleted nonsense code. Made the in between pulse reading not as noisy aka the light bulb doesn't go crazy!

>> Pulse Sensor Digital Filter <<
This code is the library prototype for Pulse Sensor by Yury Gitman and Joel Murphy
www.pulsesensor.com
>>> Pulse Sensor purple wire goes to Analog Pin 0 <<<
Pulse Sensor sample aquisition and processing happens in the background via Timer 1 interrupt. 1mS sample rate.
The following variables are automatically updated:
Pulse : boolean that is true when a heartbeat is sensed then false in time with pin13 LED going out.
Signal : int that holds the analog signal data straight from the sensor. updated every 1mS.
HRV : int that holds the time between the last two beats. 1mS resolution.
B : boolean that is made true whenever HRV is updated. User must reset.
BPM : int that holds the heart rate value. derived from averaging HRV every 10 pulses.
QS : boolean that is made true whenever BPM is updated. User must reset.
Scale : int that works abit like gain. use to change the amplitude of the digital filter output. useful range 12<>20 : high<>low default = 12
FSignal : int that holds the output of the digital filter/amplifier. updated every 1mS.
See the README for detailed information and known issues.
