Digital Electronics - Basic deals with the basic logical elements, number system,combination circuits and switches. The practical exercises are carried out on the connection board and on a completed printed circuit board connected as a house alarm. Fault finding is also possible with the house alarm.

HOUSE ALARM MODULE - Order Code - M00013

Contains all the functions of a house alarm. The functions of an alarm system are learned step by step so making fault finding more easy to understand. Altogether 8 faults can be simulated. The alarm connections are built around normal digital components, e.g. logic gates, comparators, shift registers, counters, different types of switches and decoders. The lab card is connected to the Base Unit.

LAB FLEX SET SHROUDED PATCH CORDS -  Order Code - M00011
01.    2mm Patch Cord Red 50cm 10nos.
02.    2mm Patch Cord Black 50cm 10nos.
03.    Connecting Wire 5 colors 1mm2. 1 mtr. each

In the diagram below G1 is used as a data input where G2A=G2B=L. How should A,B and C be set if the data at G1 shall be sent out on the lead connected to Y5? 

As can be seen in the diagram, an extra function has been added, LED that will indicate when the alarm is active. The LED has a self blinking action built into the circuit.
