Space War

Project Number: 19

Parts Needed For Circuit: B1, 5, U3, 4, 3, SP, 3, S2, 3, S1, 2

OBJECTIVE: To introduce you to the space war integrated circuit and the sounds it can make.

Description: Build the circuit shown on the left, which uses the space war integrated circuit (U3). Activate it by flipping the slide switch (S1) or pressing the press switch (S2); do both in combination. You will hear an exciting range of sounds, as if a space war is raging! Like the other integrated circuits, the space war IC is a super-miniaturized electronic circuit that can play a variety of cool sounds stored in it by using just a few extra components. In movie studios, technicians are paid to insert these sounds at the precise instant a gun is fired. Try making your sound occur at the same time an object hits the floor. It is not as easy as it sounds.
