pulseIn()

   
Examples   
int inpin = 0; 
int val = 0; 
 
void setup() { 
  pinMode(inpin, INPUT); 
} 
 
void loop() { 
  val = pulseIn(inpin, HIGH); 
}

Description   The pulseIn() method returns the length in microseconds on a digital input pin for a short period of time from 10 milliseconds to 3 minutes. It can be used to read sensors that return a pulse train like some accelerometers or rangers. The user can specify the counting on HIGH or LOW transitions. The pulseIn command stops all activity while executing.
