Neither This NOR That

Project Number: 49

OBJECTIVE: To demonstrate the concept of a NOR circuit.

Description: Build the circuit on the 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 that the LED lights in the opposite combinations of that circuit. Hence, we refer to it as a NOR circuit (short or "NOT this OR that"). Like the OR and AND, it is an important building block in computers.
