Hi all and sorry for my bad english,
I am a student and I would like to build a bargraph that would look like something like that :
**broken link removed**
I have heard of the LM3914 and I can find the bargraph itself. Something I don't know is how to make the light work... without noise (the LM3914 needs noise to work, doesn't it?).
I need to make it work with a 3v batterie (CR2032 ) or a standard 9v.
Is there any other component than the LM3914 that would fit better my project?
I have read data about the MM5452 and it seems to work without "load signal", what do you think of this?
Thanks !
