Which speaker and piezo-buzzer to use?

Can I just confirm that these are the correct components to use? (apologies if you also sell them, I couldn't find them with a quick search!)

The speaker looks correct, we did not install the buzzer. It does look about right from the spec.

The speaker looks right, and the piezo should work as well. The piezo connection is actually just one of the PWM-capable pins (D9) broken out with a handy GND connection, so you can use it to drive whatever Arduino-compatible piezo module you like. For eg, this one:

Or if you prefer visual indication it could switch an LED, or you could switch a regular buzzer using a transistor, or whatever. I didn't have a specific plan for it beyond being a flexible output option for notifications.
