Just finished installing 8 red leds using 2n2222 last night.
I encountered something, at the start up lights are at their dimmest light but i was expecting that if music came they will shine the brightest but instead they went off totally and never came back.
When i put it to hold mode and turn it on again they are at they dimmest then same thing happened when i play music they went off.
What could it be? i am using 500 ohm resistor for all eight, i hope someone can help me.
