Pulse Sensor Troubleshooting
So as you know I have had an extremely hard time getting the Pulse Sensor to cooperate with my computer (much like Mike).
I do believe I have found the largest source of my problem though. The speakers that we purchased from SparkFun severely interferes with the PulseSensor signals. I have a few videos that I will post demonstrating the trouble that the speakers gives me.
When playing a single tone in unison with the LED everything is fine, but as soon as you step up the complexity of the speaker all hell breaks loose and the sensor goes into a frenzy.

Did adding the 300 ohm (what you had on hand) resistor to the speaker help with the noise level of the PS reading? Ideal resistor for the 0.25w 80ohm speaker is 100ohm resistor for Arduino. But 300 ohms will work, it will just make the sound more dim.

I haven’t yet but I will tonight and let you know how that pans out.
