This file describes several digital circuits which use some of CircuitMaker's
animated components.
Circuit Description and Operation
------- -------------------------
4X4.CIR This file contains a circuit that will decode a 4x4 switch
matrix. When this circuit is simulated, the Hex Display
will indicate the key that is currently selected. To select
a different key, simply click on it.
STEPPER.CIR This file contains a circuit that demonstrates the operation
of a simulated stepper motor. The simulated stepper motor can
be connected in unipolar or bipolar mode and can be driven in
full steps or half steps.
MUX7SEG.CIR This file contains a circuit that demonstrates the principle
of multiplexing. It contains a common-anode and a common-
cathode 7-segment display which share the same data lines.
When this circuit is simulated, the 7-segment displays are
driven one at a time. To reduce flickering, the delay value
associated with each 7-segment display can be increased to
simulate a higher multiplex frequency.
CARS.CIR This file contains a circuit that will time a simulated
pine-wood derby car race. To start the race, click on the
start button. To run the same race again, click on each
reset button and then the start button. To run a different
race, click on the circuit reset icon and then the start
button.
ROCKET.CIR This file contains a circuit that will set off a simulated
model rocket. When run, this circuit will count begin by
counting down from 9. When the count goes below the warning
count, a buzzer will sound. Then, if the arm switch is on,
when the count reaches 0 the rocket will take off.
ALARM.CIR This file contains two simple examples of burglar alarm
circuits. The open-circuit burglar alarm demonstrates the
principles associated with logical "OR" operations and
parallel circuits while the closed-circuit burglar alarm
demonstrates the principles associated with logical "AND"
operations and series circuits.
The windows in these circuits can be opened and closed,
and the switches can be toggled by clicking on them.
When the simulator is running, the alarm buzzer will go off
if the alarm is enabled and one or more of the windows are
opened.
ALARM1.CIR This file contains an open-circuit burglar alarm which has
an exit delay and latched alarm. The exit delay portion of
the circuit causes a delay to occur between the time the
alarm is enabled and the alarm can be set off. In a real
burglar alarm this function allows a person to enable the
alarm and exit without setting off the alarm.
When the alarm has been set off, the latched alarm portion
of the circuit prevents the buzzer from turning off until
the reset button is pressed. In a real alarm, this function
prevents the burglar from turning the alarm off.
The exit delay in this circuit is set by selecting a Hex Key
by clicking and entering a hex number by pressing 0-9 or A-F
on the keyboard.
ALARM2.CIR This file contains an open-circuit burglar alarm which has an
exit delay, latched alarm, and an entry delay. The entry delay
prevents the buzzer from immediately going off when the alarm
in triggered. In a real burglar alarm, this function allows a
person to enter the area protected by an armed burglar alarm
and turn it off before it sounds an alarm.
ALARM3.CIR This file contains an open-circuit burglar alarm which has an
entry delay, exit delay, latched alarm, and an reset lock. The
reset lock will turn the burglar alarm off when the correct
combination is entered. In a real burglar alarm, this function
will prevent anyone that does not know the correct combination
from resetting or turning off the burglar alarm.
