Assignment: Tone Output with Arduino

Step 1: Only 1 speaker outputs audio?

Step 2: Both speakers output audio!

Result:

Making sound!

Reflections:

I’d love to apply this speaker lab to an interactive project in which conductive materials can trigger the sounds to the speakers. My original idea was to create two drum pads from the speakers themselves, by adding conductive mesh (glued taut onto the speakers). By striking the speakers with conductive drumsticks, the mesh over the speakers would output audio as they are being touched with each drumstick. A problem I’ve run into so far revolves around speaker models and the various resistance between different models. Some questions I have include:

  • How do I know what components I need for different speakers?

  • Should I edit my Arduino code to reflect the more powerful speakers?
