Hey everyone, my 1st post.
Im trying to make a led vu meter using the lm3915 IC. ive built 2 of them using circuits from 2 different websites. They work, but not as good as i hoped they would. I have nothing connected to pin 9 yet all the leds seem to light up, I.E. like it is in bar mode (not Dot mode). also it is not very responsive to the music, usualy all leds up to around 7 and 8 turn on. I have tryed using audio from my xbox, discman and my PC.
So the problem is - Bar mode when it should be in dot mode and is also not very responsive to music. Have tried rock, rap and techno.
Anyone know what might be wrong with it ?
