Is this possible? My question yesterday led me to this circuit using an NPN transistor for the buzzer: https://elinux.org/RPi_GPIO_Interface_Circuits#Output_circuits
It's actually more like this: http://www.sunrom.com/media/content/598/drv.jpg with the diode. and using a 3.3 V power supply (since that what my buzzer takes)
My question is, how do I modify my circuit to light up my green led simultaneously with my buzzer? I tried just moving the input wire to the LED's gpio pin instead of the dedicated buzzer pin and the light stopped working when the buzzer sounded.
Thanks for all the help sofar guys
