Gravity: Digital Vibration Sensor

What's the simplest way to check vibration with Arduino? Use a vibration sensor from DFRobot. You can directly plug it on our IO Expansion Shield V7 . Just vibrate this sensor, Arduino can receive a digital signal. It's easy to account and program in Arduino .

Despite it's simple, you can make full use of it with creative thinking, like step counting, Crash warning light and so on.
