Hello;
I am using your code in the hope of attaching an animation to correspond with the heart rate.
However it doesn't work and I am totally new to python coding. could you help?
here is the code…

1. Change the title to: PulseSensor HRV Biofeedback.
2. Change the main graph from IBI to BPM, and graph it as a bar graph.
3. Change the graph under the circle to HRV, with a bar changing its heigh…

What steps will reproduce the problem?
1. Download Processing IDE
2. Open Pulsesensor code for processing
3. Attempt to run the P_PulseSorsor_06 code
IDE claims there is no function 'port.readStr…
