THE MEMORY CIRCUIT

Another very useful example of "feed-back" is the Memory Circuit.

Put the Logiblocs together as shown. As soon as you press the top
BUTTON the signal will go right around the circle and feed-back into the OR
block. Because the OR block will accept a signal from either of its two
inputs, the signal will carry on going around the circle even if you stop
pressing the BUTTON.

To re-set the system you have to break the
feed-back loop by pressing the other
BUTTON. This makes the NOT block
go off. This then stops the signal going
through the AND block because this
needs both inputs before it will send the
signal on.

This is known as a "latch" circuit because it locks
in place like a door latch.

34

You can use this Memory
Circuit with any of the
sensors for light, sound or
touch. Simply plug them in
instead of the top BUTTON.
The bottom BUTTON will
then be the way you can
re-set the system.
