    Hey guys!

    Im having some trouble here in my Digital Techniques course.
    Were in the process of laying out our schematics for a AND gate with 2 input's, controlled by a SPDT switch, and im having some troubles with labelling the pins on a schematic (and knowing where to put the numbers) and then actually physically hooking it up to a breadboard with a 4 SPDT switch and a test level logic circuit with 2 LED's.

    Can anyone give me any pointers for helping me to visualize this? Maybe a resource or a video that I haven't been able to find yet? Thanks alot in advance!!!

    Here is a site I used myself. You can also go to the home page and see a lot more. On an AND gate (2 input) you have 2 inputs and an output pin. Look at a datasheet and find the pinout diagram. VCC is power, gnd is the ground. A and B are inputs, Y is the output. The idea is to use a switch to change one of the inputs from high to low. (VCC to GND)

    Basically the Data Sheet of any chip should have the pinouts of chips, if that is what you're after.
