| Piezo film sensor (msiusa.com) by BARRAGAN <http://barraganstudio.com> A Piezo film sensor can be used to measure a wide variety of phenomena, including pulses, vibration, pressure etc. This example reads values from a piezo film sensor connected to the analog input pin 0. The value read from the sensor is proportional to the amount of vibration that hits the sensor surface. The value read is printed through the serial to be monitored in the console.

    {
      val = analogRead(0);          // read analog input pin 0
      Serial.print(val, DEC);       // prints the value read

      delay(100);                   // wait 100ms for next reading
