I want to create a circuit board with 50 LEDs, 25 is for left channel and 25 is for right channel. The LEDs will blink on music. Without any complex electronics. I've already made it, but the power is too low. I've used 9 LEDs, 9V Battery, TIP-31 Transistor, 3.5mm Audio Connector (male) & Vero Board. How can I do this?
