The newest vibration module in the DFRobot "Gravity" series gives you in-depth understanding of vibration motor principles. This module uses a high quality small vibration motor that is the size of a coin. Using the Gravity 3 pin interface, you can plug and play this module for your convenience. Specification    Operating Voltage: 5v  Control mode: High‐Low level/PWM signal  Dimension: 30 x 22 mm/ 1.18 * 0.78 inches  Board Overview Pinout   Num  Label  Description   1   Signal   Control signal input   2   VCC   VCC   3   GND   GND   Pinout  Tutorial 1.

Vibration is created by a set of adjustable weighted blocks attached to the end of rotating shaft. The centrifugal force generated by high speed rotation of the shaft and weighted blocks creates vibration. Control the Module by the Switch   push button control diagram  /*************************************************** * Vibration * **************************************************** * This example shows that the module will vibrate for 5 seconds when we pres s the button * @author Dongzi(1185787528@qq.com) * @version * @date V1.0 2016-5-26 * All above must be included in any redistribution * ****************************************************/ const int buttonPin = 8; // the number of the pushbutton pin const int VibPin = // the number of the Vibration Module pin 11; int key=0; void setup() { pinMode(VibPin,OUTPUT); // Set the digital pin(11) as output pinMode(buttonPin, INPUT); // Set the digital pin(8) as input } void loop() { key=digitalRead(buttonPin); if(key==LOW) { digitalWrite(VibPin,HIGH); //Turn on the Vibration Mod ule delay(5000); //Waits for 5 seconds digitalWrite(VibPin,LOW); //Turn off the Vibration Modu le } else digitalWrite(VibPin,LOW); //Turn off the Vibration Module // put your main code here, to run repeatedly: } Results: when the button of pin 8 is pressed, the vibration module will be on for 5 seconds, then stop and wait for the button to be pushed again  Control the Module Amplitude       //Arduino Sample Code for Vibration Module //www.DFRobot.com //Version 1.0 #define Vibration 3 //define driver pins void setup() { pinMode(Vibration,OUTPUT); Serial.begin(9600); //Baudrate: 9600 } void loop() { analogWrite(Vibration, 160); //PWM delay(1000); analogWrite(Vibration, 200); delay(1000); analogWrite(Vibration, 255); delay(1000); //PWM //PWM } Results: With the PWM value increases, amplitude increases FAQ For more questions or interesting projects, you can visit the forum!
