35. Triple Input ‘AND’ Gate
Build the circuit on the left, turn the
switch (62) ON, press and hold the press
switch (61) to turn it ON, and move the
magnet (7) towards the reed switch (83).
Only when all three switches (INPUTS) are
ON (True) will the lamp (OUTPUT) be ON
(True). Electronic AND Gates can have
two or more inputs but the function is still
the same. All inputs must be True (ON)
for the output to be True (ON).
36. Triple Input ‘OR’ Gate
Build the circuit on the left, making sure
all switches are OFF. The lamp (76)
should be OFF. Turn ON any one of the
switches and the lamp will be ON. To turn
off the lamp, all of the switches must be
OFF. Electronic OR Gates can have two or
more inputs but the function is still the
same. All inputs must be False (OFF) for
output to be False (OFF).
