Project #49
OBJECTIVE: To demonstrate the concept of a NOR circuit.
Build the circuit at left and test the combinations of the slide switch
(S1) and press switch (S2). If you compare it to the OR circuit in
Project #47, you can see the LED lights in the opposite combinations
of that circuit. Hence, we refer to it as a NOR circuit (short for “NOT
this OR that”). Like the OR and AND, it is an important building block
in computers.
Neither This NOR That
Project #50
OBJECTIVE: To demonstrate the concept of a NAND circuit.
Build the circuit at left and test the combinations of the slide switch
(S1) and press switch (S2). If you compare it to the AND circuit in
Project #48, you can see the LED (D1) lights in the opposite
combinations of that circuit. Hence, we refer to it as a NAND circuit
(short for “NOT this AND that”). This circuit can also have more or less
than two inputs, though when it only has one input it is referred to as
a NOT circuit. Like the OR, AND, and NOR, NAND and NOT are
important building blocks in computers.
NOT This AND That
