8 | The AD8232 Heart Rate sensor is a low cost EKG/ECG sensor. This example shows
9 | how to create an ECG with real time display. The display is using Processing.
10 | This sketch is based heavily on the Graphing Tutorial provided in the Arduino
11 | IDE. http://www.arduino.cc/en/Tutorial/Graph
12 |
13 | Resources:
14 | This program requires a Processing sketch to view the data in real time.
15 |
16 | Development environment specifics:
17 | IDE: Arduino 1.0.5
18 | Hardware Platform: Arduino Pro 3.3V/8MHz
19 | AD8232 Heart Monitor Version: 1.0

21 | This code is beerware. If you see me (or any other SparkFun employee) at the
22 | local pub, and you've found our code helpful, please buy us a round!
