This Arduino code is used to calculate the Heart Beat from the Pulse Sensor module (https://pulsesensor.com/) and display the values as well as the Waveform on a 128x32 OLED display.

Code has been tested on Arduino Uno and Nano.

Pulse sensor Out to Arduino A0

OLED SCL to Arduino A5

OLED SDA to Arduino A4

VCC to +5v

Gnd to Gnd

This code is for Pulse Sensor Amped by Joel Murphy and Yury Gitman.Basic credits goes to them for creating the basic codes to calculate the Heart Beat.
