Materials List
1 2-Snap Wires
1 4-Snap Wire
1 5-Snap Wire
1 Battery Holder (B1)
1 LED (D1)
1 100 Ohm Resistor (R1)
1 Slide Switch (S1)
1 Press Switch (S2)
Which combination makes the LED go on? _______________________________________
This is called a NOR circuit, which is short for NOT this OR that. Like the OR and AND, it is an important building block in
computers.Compare the TRUTH TABLES for the OR and the NOR. What do you notice about the D1 Column?
_____________________________
Build the circuit as shown.
Test the combinations of the slide switch
and press switch.
