Control Vibration with Arduino: Example Code & Guide ?

This tutorial guides you on controlling a micro vibration module's amplitude using Arduino, focusing on PWM signal techniques and providing practical examples.

Tutorial

Introduce the operating priciples of the vibration module.
Introduce control mode of the micro vibration module by simple examples and pictures.(high level work, low level stop).
Control the module vibration intensity by the PWM signal.

Sample Code

//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);   //PWM
  delay(1000);
  analogWrite(Vibration, 255);   //PWM
  delay(1000);
}

Results

as the PWM value increased, amplitude increased
