Analog signal

Hi can I know why my grove sound sensor didnt give 1023 value once I play around with the potentiometer. but when i try with other type of sound sensor it works.

Do you seriously expect a sensible answer based on the information you’ve provided?


i know but the grove model read up to 0-400 and i used the sensor without connecting to nc pin, is it okay?

You won’t get a sensible answer without providing more information.

I suspect that this has very little to do with Blynk, and is more of a question for a Grove forum.
Unless you start to provide more in formation and explain why you believe that this is a Blynk related issue then I’ll close this topic.
