How to turn on all ADC's in Arduino

I am working on Arduino UNO. I am stuck at a point where I need to turn on the ADC pins on it. Please help me out, I am new to Arduino.

Solution

  • by default the A0-5 pins are HiZ input and ready to sample their A2D's. You need to simply sample them whenever you want.

    ...
int sensorValue0 = analogRead(A0);
int sensorValue1 = analogRead(A1);
int sensorValue2 = analogRead(A2);
int sensorValue3 = analogRead(A3);
int sensorValue4 = analogRead(A4);
int sensorValue5 = analogRead(A5);
