16. BUZZER

The buzzer is controlled by a triode. When it is low, the triode is turned on and the buzzer
sounds. When it is high, the triode is turned off and the buzzer does not ring. For the sake of
convenience, we are between the buzzer and the FPGA. A jump cap (CB1) is added. If you
hate the buzzer, you can remove the jump cap. The schematic diagram is shown in Figure
16-1.
