Brand New First Post - Wav Trigger

Sensors Sound & Audio
1

Just ordered a couple of these yesterday so dont have them in my hands yet but thought it might not be a bad idea to ask upfront a few questions:

  • Are there any gotcha’s with these boards that folks typically run into?

    Are there any pre-made containers that this board can be mounted in?

    Planning to put this in a car to trigger sounds and sounds like this unit needs to run at 5v. What would be recommended to lower the voltage in a car (typically 13.3v) down to the required 5v?


    • Ftdi board - i have no experience with this (dont even know what the acronym is yet) anything i need to be aware of?

    im sure i will have more questions once i get the boards but wanted to be proactive if possible to try the have good success first time out.

    Thanks for any info !

    https://www.robertsonics.com/wav-trigger has all of the info/gotchas; the main thing is to ensure properly configured/formatted SD card and filenames

    You can use a ‘stepdown converter’ to decrease the voltage to a more friendly level
