Hey
I'm trying to build these projects: Music LED Light Box or Blinking leds (they are really the same project) that take audio and make an LED or a series of LED's blink with the beat or rhythm. I can get it to work, except the LED's are very low and are very dim and do not blink with the intensity in the video. I am using two 9 V batteries in series at around 17V and the LED's are fine because if I connect them to a source and a resistor, they get around 20-30mA of current which is ideal. In the setup I have now where they are very dim, they get only around 1-4mA MAX which is the problem for obvious reasons.
Anyone know a reason which could be giving me such a low amount of current? I've tried changing the voltage, but when I had 9V's in there, it did not make much of a difference and when I have 17V in there, it is still at the same intensity.
Thanks
