This week I developed the software for the alarm. In my project the alarm is used to activate the sprinkler.
To demonstrate the alarm I constructed a test circuit using Snap Circuits.
Snap Circuits is a series of kits manufactured by Elenco that help children explore electronics.
The kit we have in our household is Snap Circuits Arcade.
While technically a toy I find Snap Circuits is an easy and fun way to put together a test circuit.
The test circuit I constructed to test the alarm is pictured below.
Also feel free to admire the classy polka dot patterned table cloth. 
To see the Alarm in 'action' follow the link below.
