Circuit TheoryTurning sound to light using a transistor
The LED’s illuminates when the circuit detects a high amplitude waveform. It can be connected to a Walkman, ipod, Phone, mini radio with earphones. This waveform is amplified by a transistor which acts as an electronic switch turning on and off the LED’s to the sound/loudness of the music

Circuit Theory
Part A: MUSIC TO Light. The LED’s illuminates when the circuit detects a high amplitude waveform. It can be connected to a Walkman, ipod, Phone, mini radio with earphones. This waveform is amplified by a transistor which acts as an electronic switch turning on and off the LED’s to the sound/loudness of the music.
Part B: SOUND. The second channel can be connected to produce sound through a small speaker.
