Pinout for Port Registers on Arduino Mega

hi there;

i got arduino mega adk , looks pinout adk different

http://forum.arduino.cc/index.php?topic=45329.0

code: [select]


void setup() {
  // put setup code here, run once:
  pinmode(5, input);
  serial.begin(115200);
}
void loop() {
  // put main code here, run repeatedly:
  serial.print("porte3: ");
  serial.println(bitread(porte, 3));
  serial.print("digir5: ");
  serial.println(digitalread(5));
}


my output is:
porte3: 0
digir5: 1

why?

thx

you current pin state pin registers, not port. input pin nothing connected can read high or low @ random - it's floating, pick noise environment antenna.
