Analog Input

Using Arduino Microcontrollers
13

if your code used
pinMode(D14, OUTPUT); to D19 (the analog pins)
you must use
Code:

pinMode(D14, [b]INPUT[/b]);
digitalWrite (D14, LOW);

to make A0 thru A5 inputs for analogRead to work correctly.

Then I am confuse for this again. If the new sketch starts, so the analog pins will be back to default which is as input pins. So why should I add this anymore ? Getting real confuse now ><
