Thread: ADC input and output

When I open the ADC box I notice its written adc0 to adc3. On the settings it shows adc1 to adc4. Is adc0 corespond the output to adc1 and adc1 corespond to adc2? I know it might sound like stupid question but I got to ask and confirm. If not connected to anything the adc ouput alwys show number in 1000's that go up and down

Thanks.

Yes, adc0 corresponds to adc1, and so forth.
