| Apr 24, 2023 at 8:06 | comment | added | Dominykas | Update: I tried removing R24 resistor and shorting pads. No buzzing sound, but when I short buzzer ( I know that I am basically shorting 5V to ground this way) some audible sound comes out of buzzer. Osciloscope shows 5V to 4.5 V pulse signal on drain. Maybe someone can explain what is going on here? | |
