transistor circuit with less batteries- Help please
First of all, I'm working with a very limited selection of components, not all of which I've completely identified.
I'm trying to set up a buzzer circuit using a latching transistor to trigger it and leave it on. The problem I've run into is that apparently the transistor can't handle that much load and it doesn't latch. I've solved that by adding another transistor(I think, that's the part I'm not sure about, it works like a transistor, but the legs are setup differently.). With the other transistor in the circuit, the first transistor latches fine, but I have to add another battery to the circuit to function all of that. I've tried a couple different ways to setup the circuit with just two batteries but can't get it to work. I don't see why I can't set up one of the batteries to activate the transistor and to sound the buzzer after it trips. Is it possible? Any help would be appreciated.
