I have a Pulse Sensor from (http://pulsesensor.myshopify.com/pages/code-and-guide) and have downloaded the latest Arduino code and Processing code, however when I run the code my serial monitor prints out characters that do not make sense to me, see picture. Also, when I run the processing code, I am able to get the heart rate window BUT there is no heart rate.
Thanks for your prompt response, after making the change, the serial monitor began printing what I believe is readings that are more sensible, but LED pin 13 blinks like crazy fast. However, when I run the Processing sketch, I get no heart rate readings as if the arduino and processing were not communicating.
As far as the processing goes, I downloaded the file for P_PulseSensor_06 and simply ran P_PulseSensor_06, KeyPressed, and SerialEvent as one sketch (see picture).
