This is a diagram designed for a personal physics exam. Feel free to point out any ways to make the circuit more efficient if you want to. The exam instructions are as follows
--Scenario
You work in a hardware store divided into the store and the storage room. The boss confides in you that the physical inventory does not match the computer inventory this month. The boss wants you to devise a way to control access to the storage room.
--Supplies Light bulbs Switches Batteries Buzzers A large amount of wire
--Requirements 1. The circuit contains a master on/off switch 2. The circuit must have a day and a night setting 3. If someone opens the inside storage room door during the day a silent light turns on at the front desk 4. If someone opens the inside storage room door at night an alarm sounds 5. if someone opens the storage room window or the outside door during the day an alarm will sound and a light turns on at the front desk to tell if it is the door or the window 6. if someone opens the storage room window or the outside door during the night an alarm will sound and a flood light turns on outside the window or the door respectively.
