The DRV2605 from TI is a fancy little motor driver. Rather than
controlling a stepper motor or DC motor, its designed specifically for
controlling haptic motors - buzzers and vibration motors. Normally one
would just turn those kinds of motors on and off, but this driver has
the ability to have various effects when driving a vibe motor. For
example, ramping the vibration level up and down, 'click' effects,
different buzzer levels, or even having the vibration follow a
musical/audio input.

This chip is controlled over I2C - after initialization, a 'string' of
multiple effects can be strung together in the chips memory and then
triggered to actuate in a row. The built in effects are much much
nicer than just 'on' and 'off' and will make your haptic project way
nicer feeling.

According to the product page, it can be used with both LRA (Linear
Resonance Actuator) and ERM (Eccentric Rotating Mass) type motors.

We put this nice chip onto a breakout board. it works with both 3V and
5V power/logic, we have code specifically for Arduino but porting it
to any I2C-capable processor should be quite simple. Check it out and
get buzzing!
