Space War Flicker

Project Number: 54

OBJECTIVE: To build a circuit using the space war IC to make exciting sounds.

Description: Build the circuit shown on the left, which uses the Space War IC (U3). Set the slide switch on and the speaker (SP) makes exciting sounds. The output of the IC can control lights, speakers, and other low power devices. You may replace the speaker with the 2.5V lamp (L1), and the bulb will flicker. You can also use the LED (D1) place of the lamp (position it with the "+" side towards 6-snap).

(NOTE: If you use the LED (D1) in place of the lamp (L1), you are actually doing Project #77).
