This is a very interesting and potentially enormously helpful project for a small girl who is in recovery from a heart condition due to a virus. What has been advised would help is a small device that can be put into a soft toy that will actually beat a like a heart at chosen frequencies.
I am a beginner at this but could solder a circuit together if someone could help.
So I imagine an oscillator that then would feed some sort of vibration device - it needs to pulse/ vibrate/ beat - rather than just be an audio frequency - so not sure what this is. But all help and suggestions gratefully received.
