Step 4
Now you have made the Memory Circuit and your sensor on your door you
will need to check that the system is working OK. Open the door and make
sure the system is triggered. Remember that the Memory Circuit will capture
even the shortest trigger. Have fun !
Step 5
(Optional)
When your door alarm is working really well it could be time to add to the
system. The Logiblocs can also turn on other things such as motors and
lights using the OUT. Add the OUT on to your system and check that it
clicks when you open the door. This clicking is the sound of the relay
inside completing the circuit between the two terminals.
Note, the OUT does not provide any power output itself, it just
completes the circuit. You will need a separate battery supply
to drive any lights or motors that you want the Logiblocs
to control. Maximum current rating 1A.
Try fixing up the bulb and socket so that
the light will shine when the door is
opened as well as or instead
of the BLEEP alarm. You will
need a 1.5V AA (LR6)
battery and three wires.
Keep the Memory Circuit you have made fixed together and store it carefully
in the Logibloc box. You will use it time and time again !
