233. Motion Detection Alarm
Replace the switch (62) with the reed switch (83) in project #213. Hold
the magnet (7) near the reed switch (83) and you will hear the siren
from the speaker (93). This circuit simulates motion detection alarms
that are in your house.
234. No Touch Special Effects
Replace the switch (62) with the reed switch (83) in project #213.
Place a 4-wire (4) across points C and D and when you hold the magnet
(7) near the reed switch (83) you will hear a gun shot and machine gun
sounds. This demonstrates how special sound effects can be activated
and deactivated without physically having to touch a switch on the circuit.
235. Proximity Warning
Replace the switch (62) with the reed switch (83) in project #213. Place
a 4-wire (4) across points A and B and when you hold the magnet (7) near
the reed switch (83) you will hear the sound of an emergency re siren.
The magnet (7) on the reed switch (83) could be like sensors on your car
that activate a warning sound when it gets too close to an object.
236. Space Battle Sounds
Replace the switch (62) with the reed switch (83) in project #213.
Place a 4-wire (4) across points E and F and when you hold the magnet
(7) near the reed switch (83) you will hear space battle sounds. Many
movie sound effects are made electronically like this.
237. Proximity Music Interrupt
Replace the switch (62) with the reed switch (83) in project #213.
Place a 4-wire (4) across points G and H and when you hold the magnet
(7) near the reed switch (83) you will hear music. Move the magnet (7)
away from the reed switch (83) and the music will stop and reset. This
circuit could simulate a disc jockey who holds a magnet and just wave
their hand over the reed switch to restart a song.
