Building the Working Model

With very limited programming knowledge, I choose to create the model solely through electrical and mechanical means.   The idea was to somehow to create a mylti-position switch that would pull in relays which would then operate the various LED and speaker.  

The choice to operate the model by means of relays were found to be increasingly difficalt and far more complex than originally thought. It would be vastly improved using Audrino which would work by mean of simple program.

The mutiposition switch made form a spring hinge. On the spring hinge the are four screws which operate each there own relay and help in position by the 12v battery supply. 

The group was very pleased with the model and how it demonstrated the to tell the Scenario  and proof of concept.
