    DFRobot Digital Vibration Sensor V2 SKU:DFR0027  Contents     1 Introduction 2 Specification 3 Tutorial 3.1 Connection Diagram 3.2 Sample Code 3.3 Result 4 Trouble shooting Introduction What's the simplest way to check vibration with Arduino? Use a vibration sensor from DFRobot. You can directly plug it on our IO Expesion Shield V7. Just vibrate this sensor, Arduino can receive a digital signal. It's easy to acount 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. Specification             Wide voltage range from 3.3V to 5V Standard assembling structure (two 3mm diameter holes with multiple of 5mm as distance from center) Easily recognitive interfaces of sensors ("A" for analog and "D" for digital) Icons to simplely illustrate sensor function High quality connector Immersion gold surface IO Type: Digital Switch life: up to 10 million seconds Open circuit resistance: 10Mohm Supply Voltage: 3.3V to 5V Interface: Digital Size:22x30mm Tutorial Connection Diagram   Sample Code #define SensorLED 13 //Connect the sensor to digital Pin 3 which is Interrupt s 1. #define SensorINPUT 3 unsigned char state = 0; void setup() { pinMode(SensorLED, OUTPUT); pinMode(SensorINPUT, INPUT); //Trigger the blink function when the falling edge is detected attachInterrupt(1, blink, FALLING); } void loop() { if (state != 0) { state = 0; digitalWrite(SensorLED, HIGH); delay(500); } else digitalWrite(SensorLED, LOW); } //Interrupts function void blink() { state++; } {| 1 #define SensorLED 13 2 //Connect the sensor to digital Pin 3 which is Interr upts 1. 3 #define SensorINPUT 3 4 5 unsigned char state = 0; 6 7 void setup() { 8 pinMode(SensorLED, OUTPUT); 9 pinMode(SensorINPUT, INPUT); 10 //Trigger the blink function when the falling edge is detected 11 attachInterrupt(1, blink, FALLING); 12 } 13 14 void loop() { 15 if (state != 0) { 16 state = 0; 17 digitalWrite(SensorLED, HIGH); 18 delay(500); 19 } 20 else 21 digitalWrite(SensorLED, LOW); 22 } 23 24 //Interrupts function 25 void blink() { 26 state++; 27 } Result As shown in figure connection , plug LED and lay a finger on Digital Vibration Sensor , LED will be lightened Trouble shooting More question and cool idea, visit DFRobot Forum Powered By DFRobot © 2008-2017
