Hi, I wanted to know how I can add a 8 ohm speaker to the schematic (see the attachment below) so that the speaker beeps every second? Can you guys think of any methods of adding the speaker to this schematic which may involve an amplifier or any active device ( A device which changes the output signal, e.g 555 timer, amplifier, logic gates). Or I don’t mind any other method as long as there is a speaker beeping every second. Thank You.
