Vibration Alarm
Build the circuit as shown and turn on the slide switch (S1). The color
LED (D8) or red/yellow LED (D10) will light if the circuit is tilted or
moved. Experiment to see which tilt angles activate which LED.
If the circuit does not shut off when left alone on a flat surface, then tilt
it slightly so it turns off.
Project 13 Tilt Sensor
The tilt switch (S7)
contains a ball, which
activates contacts when
it rolls to either side due
to tilt or motion.

One side of the vibration switch connects
to a spring, and the other side connects to
a contact next to the spring. When the
switch is shaken, the spring bounces to
open or close the circuit.
