The addition of sound to a Raspberry Pi It is as simple as connecting an HDMI monitor with speakers or speaker amplified audio port placement. Nevertheless, Ben Miller wanted something simple and portable to generate simple sounds, so he used the GPIO pins of the Raspberry Pi to drive a piezoelectric element to produce sounds.
