Simple Shed Alarm

**UPDATE!!**
*30/05/2013*
Had issues with the home made keypad so make this second front panel (Top Half V2) which takes the Numeric Keypad from Maplin (http://www.maplin.co.uk/numeric-press-button-keypad-220344). It interfaces with the alarm the same way. Also I had issues with the LED's which stood off of the PCB. They broke the tracks so I also moved them to the side of the box to be better seen through the shed door's window.

A friend of mine wanted to have an alarm on his shed/garage
