Could you post some photos about the hardware?

If you modify the potentiometer can you see changes in the analog value printed in the serial monitor?

Regards.

Hello suha86,

These "random" values are the normal values.

Could you send us a screenshot with the serial output with the ECG sensor connected to the body?

Regards.
