[Computer Engineering ] Need help understanding logic gates and how to make them?
I have a logic gate assignment due on Friday and I really have trouble understanding designing the logic circuit, drawing the logic diagram of the gate design, drawing the circuit diagram, boolean expressions, truth tables, and building the logic gate circuit. I have no clue on how to do logic gates and I need urgent help before I fail. I would like to know exactly how to exactly read and wire the actual breadboard. Pictures would be nice.
NOTE: I am only in grade 10 and this is very simple logic gate experiments, so nothing too fancy or hard.
Equipment that I have: Switch, AND gate, OR gate, NOT gate, wires, small breadboard, LEDs and brown and green resistors.
Questions:
1) Design a 5 gate circuit using each of the AND, OR, NOT at least once and with at least 3 different inputs.
2) Draw a Logic diagram of the gate design (eg. A, B, C, D, W, X, Y, Z )
3) Draw a circuit diagram including the gates, power, switch, resistors, LED’s etc. (colour code each new connection) using the proper symbols
4) Create a Boolean Expression
5) Make detailed truth table (eg. A, B, C, D, W, X, Y, Z ).
6) Produce your designed logic circuit using all the wiring and circuit rules discussed in class
This is how he will mark us:
Marking
1) Design a 5 gate circuit using each of the AND, OR, NOT at least once /1
2) Logic diagram is neat, clear, and accurate /1
3) Circuit diagram includes proper symbols and all components /2
4) Boolean Expression is correct /1
5) Detailed and correct truth table (eg. A, B, C, D, W, X, Y, Z ) /2
6) Produced logic circuit using all the wiring and circuit rules discussed in class
a. Colour coded wiring /2
b. Neat, clean wiring /2
c. Correct wiring (no cross overs) /2
d. Placement of LED to indicate key inputs/outputs /2
e. Works correctly on first try at test /2
Total /17
Once again, nothing too hard as I am only in grade 10. Pictures would be extremely helpful. Also, I need help reading logic diagrams and actually putting on a legit breadboard.
Please simplify on how to do logic gate circuits please. I am really, really lost in class and I have no clue how to do logic gates. Please help :(

Hello,
For my assignment I must create a custom designed electronic logic circuit. I also need help on how to wire it on a breadboard. I do not understand how to put your diagram onto the breadboard.
Note: I am only in grade 10, so nothing to fancy.
The questions are:
1) Design a 5 gate circuit using each of the AND, OR, NOT at least once and with at least 3 different inputs.
2) Draw a Logic diagram of the gate design (eg. A, B, C, D, W, X, Y, Z )
3) Draw a circuit diagram including the gates, power, switch, resistors, LED’s etc. (colour code each new connection) using the proper symbols
4) Create a Boolean Expression
5) Make detailed truth table (eg. A, B, C, D, W, X, Y, Z ).
6) Produce your designed logic circuit using all the wiring and circuit rules discussed in class
So I have completed my logic diagram:

My truth table:
imgur: the simple image sharer
Now I have trouble determining the boolean expression, making the circuit diagram and physically making the logic gate. Wiring/building it is what I have trouble on the most. I don't know where to place the wires, resistors, LEDs, etc.
Is the truth table correct? If so, how would you wire it? Pictures would be extremely appreciated. Or if there is any website/program that can teach me exactly how to wire logic diagrams onto a breadboard.
Items: Wires, LEDs, breadboard, Switch, AND gate, OR gate, NOT gate, green and brown resistors.
I also need help on the
Thanks
