/*
 * NOTE: this test is for HFS-DC06H
 * 
 * ZMHW Changes:
 * 
 * Using pin 4. This might change depending on PCB revision. Double
 * check.
 * 
 * If the Digital Hi (reads as 1's in serial) doesn't go away, and you are using USB,
 * you might need external power. Some USB is not enough.
 * Especially when ethernet is active.
 * Ethernet draws power, even if library is not active.

  DigitalReadSerial
 Reads a digital input on pin 2, prints the result to the serial monitor

// digital pin 2 has a pushbutton attached to it. Give it a name:
int MotionSensor = 4;

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
  // make the pushbutton's pin an input:
  pinMode(MotionSensor, INPUT);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input pin:
  int MotionState = digitalRead(MotionSensor);
  // print out the state of the button:
  Serial.println(MotionState);
  delay(100);        // delay in between reads for stability
