Vibration Motors + frecuency/amplitude

[willyneverdie]

Hello guys, im new to arduino and i want to start a project with vibration motors.

Which will be a good approach to handle the amplitude/frequency of the motor ?

thanks

How do you mean?

Link to the hardware is always a good idea.

Amplitude and frequency?  Its just a DC motor.

Do you mean control/modulate the speed?

How do you mean?

hello Delta_G:

for instance, Android API offers a Class to control the phone's vibration -> https://developer.android.com/reference/android/os/Vibrator.html

Looks like you can control the strength and duration of the vibration.
I want to build something similar with arduino.

thanks

Most cell phone vibrators or pager motors are a small DC motor with an offset weight.


Easy enough to control with an arduino.  You can control the duration.  You can control the speed.

Is this what you are looking to do?
