Dear all,
for a project I‘d like to amplify heartbeat or use it as a trigger for sound. The idea is to use a heartbeat sensor and convert the signal into sound. I found some stethoscope-mics online, however the reviews usually say that those capture a lot of background noise.
Then I stumbled across the Arduino Sensor and the whole spectrum of hardware.
Right now I only have the sensor as a starting point, what else do I need to convert the signal from the sensor into sound?
If You post a link to the datasheet of that mic You might get answers instead of wild guesses. A 5volt Arduino uses a 10 bit ADC giving a resolution of some 5 mV. Microphones usually need an amplifier to read by an Arduino.

So, you're trying to convert a heartbeat from a sounds into a digital signal, pass it through an Arduino, and turn it back into a sound?
Seems like it would be easier to just amplify the sound signal directly from a stethoscope with a mic attached?
Ask any medical person. A heart beat is very noisy! Lots of valves opening and closing, lots of liquid rushing around, lots of air going in and out of the lungs, etc.
Please post a link to the sensor.

That’s the sensor I meant, the idea is to convert it’s signal to sound e.g. use it as a midi trigger signal
