Beer Tap sounds


Just after some help. I have read through some of the other posts but haven’t found exactly the answer I’m after.

Basically what I would like to do is have a sound or mp3 go off when the beer tap is pulled. I have gone through a few ideas in my head how I can make it work and have it look neat and I think the best option would be to have a motion sensor hooked up to a MP3 module where I have the sounds loaded on to. I’m happy for any other suggestions. But if I was to do it this way could someone please point me in the right direction of what would be the best components to use.



Hi Daniel, welcome back!

The simplest option I can think of for playing the audio when a pin is driven high is this FX board with builtin amp:

As for the sensor, what were you looking to detect? If your fabrication skills are up to it, a limit switch may do the job very simply when placed in the path of the tap handle:

Alternatively, provided the tap handle stays relatively dry, a capacitive sensor could be wired to the handle, and trigger the FX board when the handle is touched:

Or as you suggest, a distance sensor or motion sensor. These may be a bit fiddly to optimise, as other things can set them off. Let me know if you want more info on this option, but generally you may need to get a microcontroller involved, or put a “choke” on a PIR sensor so it only looks at a very small area

Thanks so much for your help James I will look into all these options
