So i have looked for countless hours and found nothing that was of great help.
I decided one day that i wanted to build a computer motherboard. I figured that as the years go by, i can keep adding and upgrading circuits.
The first proof-of-concept circuit i tried was a transistor switch. Worked.
Then i built a NAND Gate... Didn't work. Of the A and B inputs, when i connect B, the light turns off no matter what A is doing.
I tried trudging ahead and built a half adder... nothing. Both outputs S and C stay high no matter what.
The attached image shows the Logic chart i was following to build the circuit that i drew up...
I have no idea how to calculate the resistors needed or anything, so i guessed on the 6v(6.5v with new batteries) circuit with a 10k ohm resistor.
Any help would be greatly appreciated, and go easy i'm new
