The inputs come from the previous logic stage.I saw this on google. I don't understand where do inputs A and B take electricity from
but. . .
It's nonsense - the transistors are not saturated, they are emitter followers.

It's assumed that they're driven by other logic gates or tied HIGH or LOW to supplies.I saw this on google. I don't understand where do inputs A and B take electricity from
Only your inverter circuit should have damaged anything. Are you certain you're connecting things correctly?Looks like I burned the leds, the potentiometers, the transistors and the power source exploded. At least I have a bunch more leds, potentiometers and transistors. I need to buy another DC power source.
I bought potentiometers and not resistors because I didn't want to bother with Ohm's law to calculate the resistence needed to drop an amount of voltage. With potentiometers I can adjust the resistence. I use them to drop from 12V to 1.3V(for the LED) and to drop from 12V to 1.0V(for transistors bases)Why and where are you using potentiometers?
That's fine as long as this is a hobby. Just don't imagine this method as a path to a career.I bought potentiometers and not resistors because I didn't want to bother with Ohm's law to calculate the resistence needed to drop an amount of voltage.

I am a software engineer. Someday while programming I thought: "I can program this metal thing, but how does it actually work at physical level?" and I am trying just to understand better how is the electricity from the power outlet of my house used by this ingenious machine we use everyday. So it is a hobby and I don't really need this information in my career, however I thought it might be interesting to see how computers were invented.That's fine as long as this is a hobby
And what does AMOLED, OLED, QLED mean?We spell LED with all caps because it's an acronym for Light Emitting Diode. We also spell the acronym when we talk about them, because they're LEDs, not leds.
So that would be like me saying maybe I'll bother to learn the syntax and semantics of the language I am using to do my embedded development project. Would you care to opine on my chances of success in that enterprise?I am a software engineer.

How can I add a resistor from the transistor base to emitter? Does that mean the resistors of the 2 inputs A and B from the following image? Why I need 2 resistors and not just one and split the output of that resistor in 2?add a resistor from each transistor's base to its emitter
Sorry. I didn't understand...So that would be like me saying maybe I'll bother to learn the syntax and semantics of the language I am using to do my embedded development project. Would you care to opine on my chances of success in that enterprise?

Thank you.Hello,
Have a look at the following wiki pages:

Don't software engineers have at least one basic EE course required? EE's are required to take a programming class.I am a software engineer.
The math isn't very difficult.I bought potentiometers and not resistors because I didn't want to bother with Ohm's law to calculate the resistence needed to drop an amount of voltage.
Maybe in US. I went to the University of Automations in my country and a took Java Master of 2 years, no basic EE.Don't software engineers have at least one basic EE course required? EE's are required to take a programming class.
It is kind of hard to find the electronic components I need and if I miss the ohm value of the resistor I need I have to wait a week to get another.The math isn't very difficult.
I think you can get away without taking a basic EE course. I wouldn't swear to it though.Don't software engineers have at least one basic EE course required? EE's are required to take a programming class.

You could buy a starter kit.It is kind of hard to find the electronic components I need and if I miss the ohm value of the resistor I need I have to wait a week to get another.
To deliver something from US to Europe it takes months. I remember I bought something from ebay and it took 2 months and I had to pay vamal taxesYou could buy a starter kit.
