I’m working on a project to use a Pi Zero to control a small remote-control Excavator. It is coming along nicely. I still need to add some LEDs and some simple audio. My question for this board is around the audio options.
I want the machine to have basically two or three sounds.
- An ‘engine’ rumble.
- A reverse ‘beep beep beep’
- Perhaps a few simple tunes (‘mighty machines’ or something).
I don’t need high quality audio, so I don’t want to add a powered speaker and build a headphone jack circuit. I have almost what I want by using a piezo buzzer, but the volume is low. Perhaps I could fix that with a power transistor, but I haven’t researched that yet.
I think this device:
might be perfect, but it looks like it is designed for the arduino platform. Would this work on the Pi?
This would work, but at 20 bucks, it would be over-kill.
I can’t use a hat because I’m already using the Dark Water 640 motor driver hat.
PS. Once I’m done, I’ll post my results and how-to videos.
