Heartbeat data keeps increasing.

[rohinrohin]

I am using the exact example code from the github repo on an arduino uno.
The value just keeps increasing continuously. (seems to be some erratic readings?)

Circuit:
ARDUINO => SENSOR
GND -> -
5v -> +
A0 -> SIG

Laptop is powered through the outlet (connected to charger).

I have added a clear tape on top and bottom to shield from bad data. This data is collected as soon as the arduino is switched on with the sensor resting on the table, heart side up.

Any help is appreciated.

Hi
Please try reprogramming the Arduino with the serialVisual boolean set to false, and also run the Processing Visualizer sketch in Processing so that you can see the signal quality.
If you can, send a screenshot.

I will update the Arduino code so that it will output to the Arduino visualizer soon, and add a comment here when I do so that you can try that as well.

I am having the exact same issue. Any help will be appreciated.

I tried running it with serialVisual boolean set to false, it had the same issue

Here's a screenshot of Visualizer sketch.
