Project II - 23. Arduino Interface with Vibration Sensor

Arduino Interface with Vibration Sensor

Arduino UNO is used to read the existence of a vibration with vibration sensor, the sensor already exists on vibration sensor module with sensor output in the form of digital data (DO) HIGH / LOW. The result is displayed on the LCD, the data displayed is the number of vibrations each 5 seconds. After five seconds then either the timer or the calculation will restart and return to 0 again and so on.
