DESCRIPTION
RETIRED PRODUCT – We’ve stopped stocking this product or it has been retired by the manufacturer and is no longer for sale. This page remains available for its resources and as a source of potential interest.
The DRV2605 from Texas Instruments is a fancy little motor driver. Rather than controlling a stepper motor or DC motor, it is 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 memory of the chip 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 a 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.
The chip works with both 3V and 5V power/logic, and Adafruit has written code specifically for Arduino but porting it to any I2C-capable processor should be quite simple. Check it out and get buzzing!
