Okay.. Well I was just building an AND GATE with an n
NPN bc 548 transistors.. But it was responding to input of the transistor connected to led (turned on when the input of this transistor went high and both went high)
.i learned that a transistor has to be connected to collector base and...
I am studying in 10th grade and was building a binary counter with an XOR gate and an AND gate.. The half adder (XOR) was working properly but the and wasn't working properly.. I've build many and gates before but this was the first time.. Then I took the transistors out to check them and build...
