// Simple sketch to read the pulse width of a PWM signal
// Useful for reading PWM valuss from a R/C reciever
// to create actions that are not typically handled
// with a servo, such as controlling LED lighting.

int pin = 8;  // Check what pin to use
int output = 1; // pin to blink
int duration; // Duration of the pulse

// setup serial and input, output pins
void setup()
{

  Serial.begin(9600);
  pinMode(pin, INPUT); // PWM input pin
  pinMode(output, OUTPUT); // Output Pin

}

void loop()
{

  duration = pulseIn(pin, HIGH);
  if (duration > 150)
    {
      digitalWrite(output, HIGH);
    }
  else
    {
      digitalWrite(output, LOW);
    }
  Serial.print("Flow Value: ");
  Serial.println(duration);

  delay(100); //delay so you can read the scrolling output
}
