Card Reader
Put the blocks together as shown. When
you pass a card over the LDR block it will
trigger the SEQUENCER and so the lights will move
round one place. If you make a card with holes
punched in it then, when you pass it back and
forward over the LDR, the lights will change
quickly The aim is to get the GREEN LED to
come on but it is not as easy as it seems.
Step 1
Cover over LDR with card and press
the BUTTON several times until the
BLEEP on the SEQUENCER sounds.
The card reader is now ready.
Step 2
Pass the card with holesin it
over the LDR so that the
SEQUENCER is triggered either 2,
9 or 16 times. Note how the
DELAY (2-Way) block prevents
any fast signals getting through
to the DELAY (Long).
Step 3
Once the lights have stopped at the
DELAY (2-Way) for about one
second, the signal will go on to the
DELAY (Long). Now is your chance to get past the AND
block which was previously stopping any signals from going
through. Move the card just one space back again so that it
triggers the next position. Then the GREEN LED will
come on.
You are now clear for entry!
Change round your Logiblocs and design different
arrangements and see if your friends can work out
how to decode them!
