I would like to know if I can use a pressure sensor with an Arduino. The code will detect when the sensor is on, will start a timer, stop when the sensor is off, and display the time elapsed.

Here is the code for the timer:

int main(void) {
  LARGE_INTEGER frequency; // ticks per second
  LARGE_INTEGER t1,t2; // ticks
  double elapsedTime;
  // get ticks per second
  QueryPerformanceFrequency(&frequency);
  // start timer
  QueryPerformanceCounter(&t1);
  //the code for sensorwill be written here
  QueryPerformanceCounter(&t2);
  elapsedTime = (t2.QuadPart - t1.QuadPart) * 1000.0 / frequency.QuadPart;
  printf("\nElapsed time : %lf ms.\n", elapsedTime );
  return 0;
}
