I am currently trying to make a small circuit work, and more than just trying different things until it does work, I wanted to hopefully get an explanation to why it is not working. I am a novice, I only started dabbling in my free time recently and thought I had a decent if only vague understanding of how a NPN3904 Transistor would work. I have two separate circuits. One is a 5 volt circuit with a button on it, the second is a 6volt circuit with a coin meter on it. The button triggers a keyboard press that will eventually trigger that a coin dropped through my coin door, at this time I would like the NPN3904 turn on and flip the coin meter. For whatever reason, when I measure voltage at the emitter of the transistor there only seems to be 1 volt passing through and there for not enough to trigger the coin meter. I am using a 1k ohm resistor on the base of the transistor. What am I missing?
I am attaching a crude drawing, please explain what I am missing or how I can design this so it will work?
