So i need to make a schematic of a darkness sensor circuit with one additional feature. And that additional feature is the triggering of a sound by a buzzer when the LED is not lit. And this buzzer can be manually switched off by the user. So how do i go about this? I planned for my circuit to look something like the one this user had posted https://forum.allaboutcircuits.com/threads/dark-sensor-ldr-circuit.123567/
So my question is, how could i modify this person's schematic to what i am looking for? I need the LED to light up in the dark and the buzzer to trigger when it's bright. The buzzer needs to be able to be switched off manually.
Thanks in advance.
