63. Five Space Battle Sound

Effects

Build the circuit shown, and turn ON the

switch (62). The sounds of space battle

may turn on with the red light (LED 69)

ashing with each sound. Press the

switch (61) to step through the ve

different battle sounds.

The IC in the Three-in-One (11) has these

different sounds stored in memory and

accesses them sequentially as you press

the press switch (61).

64. Cycling Through Space Battle Sounds

Turn ON the switch (62). Press the press switch (61) and the sounds of a space battle come from the speaker (93).

Then use one nger and touch the touch plate (80) a number of times. Notice that the press switch (61) cycles to the

next sound while the touch plate (80) cycles to the previous sound. All the logic that determines what sound goes to the

speaker (93) when certain inputs are set is pre-programmed into the IC in the Three-in-One (11).

65. Proximity Warning of an Alien Craft

Replace the press switch (61) with the reed switch (83) and turn ON the switch (62). Move the magnet (7) towards the

reed switch (83), the sounds will change as a warning emulating the proximity of an alien craft. Note that because the

LED (69) is not in series with the speaker (93), it does not affect the volume of the sound.

Note: You may need to

twist the LED (69) heart

attachment to clear the

speaker (93) so it ts

properly.
