The Adafruit DRV2605L Haptic Motor Controller adds effects to haptic motor control giving you freedom to choose more interesting or informative vibrations. The DRV2605L chip has a library of 123 effects such as click, double click, ramp, and hum, including various intensities; it's a very smart chip. To make your project easier, Adafruit supply a tutorial and code library for Arduino. This should be simple to convert to any microcontroller. The board uses I2C so connecting to it is quick and simple and with Adafruit's library you should be up and running in no time. It is specified to work with Linear Resonance Actuator (LRA) and Eccentric Rotating Mass (ERM) type motors, though Adafruit have only tested it with ERM motors.
Supplied as a fully assembled board plus 1 x 5-pin male header for you to solder on if your project needs it.
Make haptic feedback motors more interesting and informative
Have different effects for different conditions rather than a single buzz
