Speaker with the oscillator bit

I have always seen the speaker with the oscillator bit, Is it necessary to have the oscillator? :wink: I don’t have the speaker but was just wondering incase I get one. :wink:

If you use the speaker with the Arduino or the MP3 player modules, then no oscillator is required… :slight_smile:

JackAndJude has two good examples. You can also use the Microphone module or the Noise bit, among others, and depending on the project. I highly recommend the Oscillator module, though, even if you don’t use it for music!
