In an audio controlled LED circuit, LEDs turn on and off according to the music. This circuit is simple and efficient, it requires a small amount of audio signal at the input, which comes from the output of the headphone socket of any audio playing devices such as mp3 player, CD player, computer, cellphone, etc. We are going to make this circuit by using 15 LEDs and a …

First it needs a current limiting resistor in series with the LEDs. Something like 150 Ω will probably do. Next, the transistor needs at least 0.7 V to conduct, which you may not have if you use a line output. If you do get the LEDs on, then add a 1 kΩ resistor in the red wire connection. (They seem to have never heard of resistors.)

An LED driver is an electronic circuit specially designed to drive or illuminate a set of LEDs safely through controlled current and voltage output, as per the specifications of the LEDs. Since LEDs are vulnerable semiconductors devices, they must be driven using a regulated current and voltage power supply.
