Space War Sounds Controlled By Light

Project Number: 121

OBJECTIVE: To change the sounds of a multiple space war with light.

Description: The space war IC (U3) will play a sound continuously. Block the light to the photoresistor (RP) with your hand. The sound will stop. Remove your hand and a different sound is played. Wave your hand over the photoresistor to hear all the sounds. Press the press switch and now two space war sounds are played. If you hold the press switch down, the sound repeats. Press the press switch again and a different sound is played. Keep pressing the press switch to hear all the different combinations of sounds.
