INA169

Goal: Measure LED current via INA169. Test voltage reading from INA169 out pin.

Hardware: Arduino Uno, LED, and INA169 (see attached photo for connections)

Software/code:
Code: Select all | TOGGLE FULL SIZE
//2020-8-28
const int INA169_OUT_PIN = A0;
float INA169_OUT_Value;
   
void setup()
{
  Serial.begin(9600);
}

void loop()
{

  INA169_OUT_Value = analogRead(INA169_OUT_PIN);
  Serial.println(INA169_OUT_Value,4);
 
  delay(1000);

}


Observations/questions:
1. INA169 out value always shows zero in Arduino serial monitor. Anything wrong with my connections and/or code?
2. The voltage between INA169 out pin and ground is about 8.4 mV, measured with a volt meter.
3. The current to/from Arduino Uno is about 12 mA, measured with an ammeter.

Thanks.
