Okay, so I am trying to use the breadboard and I have a hard time with a three input AND gate. Guess I can do a schematic
http://imageiso.com/out.php/i17298_3inputandgate.JPG
So in my bread board, I have pins 1 and 2 as inputs..with pin 3 as a LED (output), and I have a jumper connecting pins 3 and 4 cause the result of the first and gate determines if the second AND Gates lights the LED..and I have pin 5 as the input..and pin 6 in another LED..now I connected pin 7 to the ground and pin 14 to +5V..this is the problem: the first and gate works..first LED (on pin3) lights up, but the second one doesnt
I tested everything and I reconnected it to my breadboard..sorry I don't have a picture of it so I am curious why the second one won't light up..Any ideas guys?
