Pulse sensor with arduino uno+blynk

ok so i deleted everything in the loop fn except analogRead and serialprint…

when i place my finger onto the sensor, i show 0 value reading whereas i lift my hand up (nothing on sensor) will show 995 value reading…

Is that how the Push Data example in sketch builder looks?:

@Costas recommended that you look at that over a week ago.I assume that you’ve been waiting for your USB2Serial adapter to arrive in the meantime, but that shouldn’t have stopped you from researching Blynk sketch structure and realising what a proper void loop should look like.

I’d suggest that you do some more research and more experimentation then come back with your findings and your full updated sketch if you’re still having problems.
