We recently published a new tutorial for our Haptic Feedback Evaluation Kit that explores how to play music or other audio signals on a vibration motor or LRA.
Using the great new “Audio-to-Vibe” feature in the DRV2605 and the 3.5mm audio socket on the Haptic Shield, you can easily experience meaningful vibrations alongside your audio output. This tutorial shows you how to access the feature in our Engineering Mode (and of course points you in the direction of the required files). With all the necessary programming already built into the code, it’s really easy to get up and running.
Also, we look at some of the limitations of the feature and explore options for improving the performance, including a short discussion on lowpass and bandpass filters and the components you might need to start prototyping your application. So if you’re looking to play music through a vibration motor or drive ERMs and LRAs with audio files then this tutorial is a great place to start! See the link here:
It’s also worth remembering that these kind of custom circuits with vibration motors are the exact kind of design work Precision Microdrives undertakes, so if you have a project that you need expert help on then don’t hesitate to contact our engineers.
