I'm making a simple dark sensor project with a light dependent resistor (LDR) and I want to replace the LED with a buzzer but it doesn't work
I tried that and it didn't work I even lower the base resistor to 82 ohms and remove R2 and still nothing which is weird so it must be that bc 547. I think a Darlington pair will do the job, it worked in the simulation.
