Hello! I am working with pulse sensor. The LED from pin no 13 is blinking according to the pulse. Its working.
But pulse sensor amped visualizer is nor working! It just shows a straight line and not gives BPM.
I used code from this site for both arduino and processing code.
https://github.com/WorldFamousElectronics/PulseSensor_Amped_Arduino
I am using Windows 7(32 bit), arduino IED 1.6.9
And processing 3.1.1 software.
I gave same baud rate to both arduino and processing code.
Please suggest me how can I solve.
If possible please give the screenshot , how to fix it
Thanks
