I forgot, but , didn't we have the ability to allow the audio to flash LED's like on the robot B-9 chest or the Knight Rider kit? I forget.

I guess you could use it to trigger a Larson scanner (knight rider light) with it.

is what I bought for my B9 chest light. I did not go with the real neon. I used two amber truck LEDs
along with half a dozen little red side marker lights. They are all behind acrylic tubing to simulate neon.
I am getting off track here, but the point is that I have a lot of light running off of the MK114 and it works fine. It was cheap to buy and easy to put together.
Thanks everyone for their comments.
its possible to vary the level using preset resistor on card
Thanks!
What about using another microcontroller which enables output pins depending on the input voltage, connect the input up to a digital port, use a script to get the sound level and PWM to the digital port, microcontroller then enables whichever LEDs need to be illuminated based on the PWM value... Just a thought, no idea what would be needed but I'd be surprised if there wasn't an ATTiny based DIY project for something like that.
PWM is just mostly a flasher that does only one led per pwm output,witch for eyes it works well.
MOSFET works better then a transistor because is variable resistor depending on the voltage apply.
