Its better to describe ypur circuit with a schematic. We need to know the supply and arduino connections. Also please show us the code you are using.

> When you submit a question on the forum you will usually need to add a schematic (circuit diagram). The tutorial that follows will explain some ways to create a useful image; however lets start by explaining how to add the image to your post. Its easy. Having created the image all you need to do is : Save the image somewhere convenient - maybe your desktop Start your post, and place the cursor (insertion point) where you want the image to be shown; [upload image to forum] 3: click th…

To start use the example to read a value from the adc.

you will need to show us your code.
