We strongly advise that you DO NOT connect the Pulse Sensor to your body while your computer or arduino is
being powered from the mains AC line. That goes for charging laptops and DC power supplies. Please be safe
and isolate yourself from from the power grid, or work under battery power.
Connect the Pulse Sensor to: +V (red), Ground (black), and Analog Pin 0 (purple) on your favorite Arduino, or
Arduino compatible device, and upload the ‘PulseSensoAmped_Arduino-xx’ sketch.
