Raj writes that he’s just finished a new PC-based heart rate monitor using Arduino and Easy Pulse sensor (see previous Easy Pulse post). This project takes the sensor’s analog photo-plethysmography (PPG) output and feeds it into an Arduino ADC channel which converts it into digital counts which are then transferred to the PC through a serial interface. A PC application using the Processing programming language then displays the received PPG signal and instantaneous heart rate.
The Arduino and Processing sketches along with more project details can be found at EmbeddedLab.
