Serial monitor infinite output

Using Arduino Programming Questions

first of all, i want to thank all of u guys who replied in this post... kudos to all of u! :wink:

my problem is solved, although it seems that it doesn't involve the floating pin issue... i already fixed my problem by putting an inverter from my input device going to the arduino... LOL.

here's my code which makes our hexapod move in 4 directions:

#define forwardPin  12
#define backwardPin  11
#define rightPin  10
#define leftPin  9

int forwardState = 0;
int backwardState = 0;
int rightState = 0;
int leftState = 0;


void setup()
{
  Serial.begin(9600);
  pinMode(forwardPin, INPUT);
  pinMode(backwardPin, INPUT);
  pinMode(rightPin, INPUT);
  pinMode(leftPin, INPUT);
}

void loop()
{
  forwardState = digitalRead(forwardPin);
  backwardState = digitalRead(backwardPin);
  rightState = digitalRead(rightPin);
  leftState = digitalRead(leftPin);
  if (forwardState == HIGH && backwardState == LOW && leftState == LOW && rightState == LOW)
  {
