Maxuino/Arduino buzzer keyes 006

Not nearly as sophisticated though a good beginning with Maxuino and sound is the keyes 006 buzzer, which is suitable to making warning sounds. They are used in alarm systems though at screaming decibels. This one will be more quiet with the Arduino UNO driving an analog voltage. 

If you want to replicate the more complex sound in the previous patch you can use an amplified speaker or the speaker directly from your computer as opposed to this limited range piezo speaker.

Notice how when you use the slider in the patch below the tone does not change much though the volume does change.
