Cant get 2 analog input readouts correctly

[TomGeorge]

Hi,
Try this code and see if the A3 and A4 readings interact and if they are accurate.

int A3Val;
int A4Val;
int A3Pin = A3;
int A4Pin = A4;


void setup()
{
  Serial.begin(115200);
}

void loop()
{
  A3Val = analogRead(A3Pin);
  A3Val = analogRead(A3Pin);
  float A3voltage = (float)A3Val * (5.0 / 1023.0);
  A4Val = analogRead(A4Pin);
  A4Val = analogRead(A4Pin);
  float A4voltage = (float)A4Val * (5.0 / 1023.0);
  Serial.print(" A3 Value =");
  Serial.print(A3Val);
  Serial.print("\t A3 Voltage =");
  Serial.print(A3voltage);
  Serial.print("   \tA4 Value =");
  Serial.print(A4Val);
  Serial.print(" \tA4 Voltage =");
  Serial.println(A4voltage);
  delay (250);
}
