Blue LED/Top Right = NAND
Red LED/Top Left = AND
Orange LED/Bottom Left = OR
Green LED/Bottom Right = NOR
The two SPDT switches are the inputs, and the 4 SPST switches by the grounds are to turn on and off each gate, incase you only want to see one at a time.
The two LEDs at the bottom only signify the state of the inputs.
The Switch that comes after the 2.2k resistor I added because the circuit only works if it is off. It was in the original OR gate but I don't see what it did, and not it powers the Transistor when it is supposed to be off, so I kept it in just incase but it does not work if the resistor is connected.
