1. The challenge is to create a simple security system using only resistors, a very thin wire, 12 AAA batteries, and a piezoelectric buzzer.
2. The attempt at a solution
I recall reading that if a resistor is placed mid-wire in an alarm system, it will not detect any problems, such as a person trespassing or breaking in.
I did a little bit of research and came across a pdf that highlights a few points towards building an alarm.
My input source would be the batteries to provide a voltage to power the alarm. The output would be the piezoelectric buzzer. What remains is designing the system.
Can someone help me out with this? I need to do this extra credit to salvage my grade in that class.
