Adafruit vibrating mini motor disc adafruit 1201 p the adafruit vibrating mini motor disc is simplicity itself to use apply power and it buzzes remove power and it stops they will work from 2 to 5v with stronger vibrations from the higher voltage and the drive circuit can be as simple as a battery and switch if you want to drive it from a microcontroller such as an arduino then you will need a series resistor to limit the current draw please see the technical specification for details o
