Signals Needed to be monitored

I’m getting some signals directly from the drive, some signals are analog signals and some signals are digital signals, now I want to log those signals, My question is Analog signals are in the range of 0.8v to 2.8V , Now if i connect that signal to be monitored to A0 pin of my Arduino, will Arduino give exact value?

As you can see your image is too small to read. Perhaps you can just copy and paste the text?

You say "getting some signals directly from the drive" but you have not told us what the "drive" is? Can you post a link to the product datasheet?

The Arduino's ADC would read 0.8v as 1023 / 5 * 0.8 = 163 and it would read 2.8v as 1023 / 5 * 2.8 = 572

For the full details about the ADC you should read the Atmega 328 datasheet (assuming you are using an Uno)

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.

I'm getting some signals directly from the drive,

What drive?
It only because I repair and install them that I know you mean a Variable Speed Drive, VSD.
What model Arduino.

To answer you question, YES, but the raw data you get from the analogRead will need to be converted to a voltage value.

Can you tell us your electronics, programming, Arduino, hardware experience?

Thanks... Tom... :slight_smile:
