AD8495 Thermocouple Amp - Input only 1023

Post by Brennn10 »

Here is my code in the loop:

Code: Select all

 int inputValue = analogRead(A0);
    float outputVoltage = inputValue * (5.0 / 1023.0);
    Temp = (outputVoltage-1.25)/0.005;
    Serial.print(inputValue);
The inputValue is 1023, and I am not sure why.

I have V+ connected to 5V.
I have both GNDs connected to Arduino GND.
I have Out connected to A0.

Any ideas why I'd only be receiving an inputValue=1023?
Is there an LED on the AD8495? If there is, I'm not seeing any lights turn on...

Let's check the hardware just to be sure. Post a photo showing the breakout and your connections please. 800x600 images usually work best.
