Circuit to understand working of a "nor" gate

The same circuit that was built in the post "Circuit to understand working of and gate"can be made to work as a nor gate too, just by modifying the program.

The nor gate is negation of the or gate, hence we just need to add a negation to the "if" condition in the previous program of or gate in the post Circuit to understand working of and gate Here is the modified program:



Note: The truth table and animation of nor gate can be found in the post "NOR gate animation"

Now the led3 should turn on only when both the inputs are low and should remain off in all other conditions.
