11. Personal Security Alarm
Build the circuit, press the press switch (61) and
you will hear the alarm (78) sound. Hold the press
switch (61) and the alarm (78) will stay on. Some
personal security alarm devices work like this so
that a person needing help can sound a loud alarm
to alert for help from anyone who may be nearby.
12. House Alarm
Build the circuit, move the magnet (7) towards the
reed switch (83) and the alarm (78) will sound.
Move the magnet (7) away and the alarm (78) will
turn off. This simulates how a house alarm works.
