So is it that a voltage in A prevents the flow from the VCC entering and passing through the diode at A? Making it then flow to B, and if B is inactive it flows in there and gets grounded. But if B also has a voltage pushing against the diode it gets blocked there as well and passes on to the...
Thanks I will investigate further. I am very curious. I'm still kind of baffled by the ground connection. If it's blocked by a diode why even make the connection?
Some of the diagram is a bit beyond my current ability. I'm not too sure either about how electricity behaves down so many paths...
Well I did finally solve this thing. I had to modify the NOT segment by adding another transistor. I also ditched the extra transistors for the ANDs and OR, since I don't really need to control the voltage leaving the output in my crude little design. X)
I think I'm reading the diodes wrong. Am I imagining it, or do they get drawn facing differing directions at times? Look at the ones on the grounding look like they're shunting off the ground flow, but I know that wouldn't have much point. Is current flowing away from the arrow or towards it?
Oh my thanks so much for the resources. I will be ordering these next. I was mainly working with what I had from a kit, not to build anything serious, but I want to prove to myself that I can build these things and make them work in some way. Once I'm comfortable with them, I will just buy...
Diodes would be better for this? I'm actually a bit perplexed by how that even works. XD
I'm assuming I'm wrong, but looking at it my impression is that VCC would just always flow out, and the diodes would block A and B. What's the trick behind it?
Yeah, now I'm trying to actually build the physical thing out of the abstraction. I did go back and look at my drawings and I realized that I created that graphic wrong there above. Let me update that. I had an AND instead of an OR at the end.
And the abstract diagram as well. Hopefully I...
First let me just I'm a total newbie to electronics, but I would like to progressively learn how computers work by building the little components with the small parts, and then work up to the ICs once I understand how to make rudimentary versions.
I'm trying to make a 1-bit multiplexer out of...
