Voice Control

Project Number: 33

OBJECTIVE: To use your voice to control sounds.

Description: The preceding circuit probably did not seem too exciting; so replace the LED (D1) with the speaker (SP). You hear a range of exciting sounds. Clap or talk loud and the sounds will resume. If you find that the sounds do not turn off, the vibrations created by the speaker may be activating the whistle chip (WC). Set the speaker on the table near the circuit and connect it to the same locations using the jumper wires to prevent this.
