The other day someone asked me how they could integrate audio their Arduino project. The answer was easy, I just told them to use the Wave Shield Kit that we sell in the Maker Shed! This shield is one of my favorites; It allows you to play back audio files stored on an SD card. Just build the kit, load up a card with .wav files, add a speaker, and use the wavehc library to trigger playback in your Arduino sketch. The possibilities are limitless! Here’s a quick demo:
I think I’m going to build a door bell using random animal sounds like that. It will drive my labradoodle wild!
