LET’S GET CONNECTED
As you have seen we can use light and sound to trigger the Logiblocs.
This section shows you how to make systems which are triggered
by the Jack Plug and IN block.
❶
DOOR ALARM
You will need a strip of aluminium foil and some sticky tape.
Step 1
Take the Jack Plug wires and place
them near the bottom of your door
surround with their ends sticking out
so that the door will brush past
them when it is opened. Stick the
wires on with sticky tape.

Step 2
Shape a strip of aluminium foil around
the edge of the door itself, at the
height of the two wires. When the
door opens, the aluminium foil will
touch both wires which can be used
to trigger the Logiblocs into action.
This is called completing the circuit.
Step 3
Fix the Logiblocs together as shown and
plug in the Jack Plug to complete the
system. Hide the Logibloc system
you have made. Now, if anyone
opens the door, the alarm will
go off!
