Kit 12. Music – Light Modulator
http://kitsrus.com/pdf/k12.pdf
The circuit diagram shows how simple the circuit really is. The audio signal is applied across the LED of the opto-triac. The potentiometer adjusts the input sensitivity while R2 limits the LED current. The LED emits infrared light in response to the input signal. The triac driver inside the MOC3021 package is sensitive to the IR light, and activates a slave triac which controls the load.
DIY Kit 12 - MUSIC TO LIGHT MODULATOR

The diagram shows how simple the circuit is. The audio signal is applied across the LED of the opto-triac. The potentiometer adjusts the input sensitivity while the resistor is used as protection from high signal peaks. The LED emits infra-red light in response to the input signal. The triac driver inside the 3021 package is sensitive to this IR light which activates a slave triac and load.
Audio Conversion to Light LED Circuit

The circuit contains three main parts. First, an audio preamplification using transistor Q1. The electret microphone detects the sound in the surrounding and converts it into an electrical signal. This signal, then, passes through transistor Q1 to amplify. Second, an audio amplifier stage which is built around transistor Q2.
