Getting Started with LTspice

March 1, 2017

LTspice is a high performance SPICE simulator, schematic capture and waveform viewer with an impressive library of passive devices. Over 1000 models are included in the download but you can also add third party models.

Electret Mic Breakout Board Hookup Guide

June 23, 2016

An introduction to working with the Electret Mic Breakout Board.
  • For an application this specific I’d recommend you use the SparkFun Sound Detector

  • I don’t see why not - we do use a different op-amp for the pre-amplifier and we do not have selectable gain. Our specs a slightly different…just depends on your application and your gain requirements.

  • I could only find one source for the LRA type motors which is why the hook-up guide and examples are for the more common ERM type. Precision Microdrives seems to be the best place to find LRA motors.

    As far as producing a “click” you can use the waveform function, with the ERM motor, to write the waveforms of 17-45 (see page 60 of the data sheet) to produce a custom clicking effect. You can also customize these with various ramping/timing effects as well.

  • Yeah, it’s pretty bad. The timeline for this got moved up so first try at the screen recording software made it through. They are being redone and will be replaced once the advanced tutorial goes live.

  • Here’s another method for speeding up your SPICE sims that doesn’t involve the destruction of personal property.

  • Should be live now. If not, I’ll keep looking into it. Thanks.

  • In the Arduino folder in your documents there is a sub-folder called “libraries”. In libraries create a new folder called SparkFun_DRV2605L. Place the .h and .cpp files from the github download in that folder. There is a link in the tutorial on how to install Arduino libraries and this is one of the examples.

  • Thank you for finding that mistake! Tutorial updated.

  • Yes, a 5V motor was used in this project. If you would like to use the vibration motor we carry for this project then an additional switch would be needed between the 3.3V regulated power pin and the Haptic Motor Driver.

  • You’re right–Not the correct practice. The ERM vibration motor we carry operates from 2.0V to 3.6V. It works perfectly off the regulated 3.3V power pin on the RedBoard. During the prototype and test phases I was able to get my hands on several ERM motor samples which could operate from 2V to 5V. The 5V motor vibrates with with a much stronger intensity which is why I used it in my foot massage application. Thank you for having a great eye so I could update this tutorial.

    As far as a recommendation…I’m not sure what the application is. Like silently feeling when you have detected metal on a beach? Which dev board do you currently use? If you only have one regulated output at a specific voltage then you should find a motor rated for that output. Depending on how much you need to feel the vibration I’d up the rating and the number of motors. But why not make a wrist band or pin it to your body? - It would be much easier to feel it that way.
