    Professor X keeps his final exams in his Lab. For security reasons, he would like you to design an alarm system for his Lab that can be activated with a key when Professor X is not in the Lab. The Lab has a window and door that are equipped with sensors that output a one (HIGH) when they are secured (i.e., closed). When the alarm system is activated with a key, an LED should light up if either the window...

    For this problem you will analyze the updated design of the home security system from homework 4 The original home security system had a few problems: 2. Issue #1: Assuming the intruder stayed in the building longer than 30 seconds, the alarm would sound for 10 seconds then the "amber light to red light to alarm sequence" would repeat. The cause of this problem is the fact that the U2 counter will continue counting every 10 seconds. Once the counter...
