We tried using a used speaker to save some money, but after testing out a few we decided we needed to purchase a new one. We tried doing the “toneMelody” sketch to test the old ones, but unfortunately we couldn’t get any to work. We ended up ordering a speaker from the Adafruit website. The trouble shooting was at least a good opportunity to take our first stab at soldering.
Throughout all of this process we have been using the Adafruit website as a resource quite frequently. We have found tutorials, specifications, and much more that have all been valuable. Here we also learned about reformatting our SD card for the audio files we need.
