Measuring Current / Voltage using INA 219

Other Hardware Sensors
1

Hello! I am trying to make a device to measure wind speed using an arduino uno and an anemometer that i took from another device that uses 4g.
Anyways after connecting everything and uploading the code to the arduino uno, the serial always shows -8 m/s even though the anemometer is moving or even if i disconect it (i am using the A0 analog in to receive the signal
Any ideas about what could be going on?

Thanks in advance

It would be easier to help if you:

  1. said what "everything" is and how it (they?) are connected, and
  2. showed the code.

Hi,
Can we please have a circuit diagram?
An image of a hand drawn schematic will be fine, include ALL power supplies, component names and pin labels.

An image of your anemometer and its connections would also help.

Do you have a DMM?

Thanks.. Tom.... :smiley: :+1: :coffee: :australia:

That doesn't make sense.
The INA219 is a digital I2C device, and must use A4 and A5 for communication.
