# Steps
## Let's get started with pulse sensor anatomy.
media: http://s27.postimg.org/srj26m01f/pulse1.png

notes: The front of the sensor is the pretty side with the Heart logo. This is the side that makes contact with
the skin. On the front you see a small round hole, which is where the LED shines through from the back, and
there is also a little square just under the LED. The square is an ambient light sensor, exactly like the one used
in cellphones, tablets, and laptops, to adjust the screen brightness in different light conditions. The LED shines
light into the fingertip or earlobe, or other capillary tissue, and sensor reads the amount of light that bounces
back. The other side of the sensor is where the rest of the parts are mounted. We put them there so they would
not get in the way of the of the sensor on the front. Even the LED we are using is a reverse mount LED. For
more about the circuit functionality, check out the Open Hardware page.
The cable is a 24” flat color coded ribbon cable with 3 male header connectors RED wire = +3V to +5V
BLACK wire = GND
PURPLE wire = Signal. The Pulse Sensor can be connected to arduino, or plugged into a breadboard. Before we get it up and
running, we need to protect the exposed circuitry so you can get a reliable heartbeat signal.

## Preparing the pulse sensor

notes: Before you really start using the sensor you want to insulate the board from your (naturally) sweaty/oily
fingers. The Pulse Sensor is an exposed circuit board, and if you touch the solder points, you could short the
board, or introduce unwanted signal noise. We will use a thin film of vinyl to seal the sensor side. Find the
small card with four clear round stickers in your kit, and peel one off. Then center it on the Pulse Sensor. It
should fit perfectly.

## Running the pulse sensor code.

notes: Get the latest Arduino and Processing Pulse Sensor software here http :// pulsesensor . com / downloads /
Arduino code is called “PulseSensorAmped_Arduino-xx”
The Processing code is called “PulseSensorAmped_Processing-xx”
For Arduino and Processing programming environments: www .arduino.cc www.processing.org

## Pulse sensor visualizer
media: http://s29.postimg.org/vg47ls9tz/pulse4.png

notes: You should run the visualization after you run the “PulseSensorAmped_Arduino-xx” xx stands for the version number. You have to install processing environment then open it select “PulseSensorAmped_Processing-xx” file and run the file. Make sure you have selected the right version of arduino code and processing code then you have to run the processing code after arduino code also make sure you select the right USB port where the Arduino board is inserted.
