#Kitt voice box how to

Is this achievable with PWM for 60 led's? I guess I'm asking because I'm still not sure how that LED Driver works. The LED's are not simply on/off, they also seem to be more dimmed at the higher / lower section (and also left/right section, see video above).

However I'm not sure how to achieve the dimming effect. I'll probably find out how to get the LED's to behave like a VU meter by finding some sketches and following tutorials. Any hints? )ДЄnother thing I'm not quite sure about: How do I acchieve the 'LED dimm effect' (see this video > ). Is my assumption correct that I'll need to have resistors hooked up to every single LED? I will have to go through some tutorials to figure out how to use the LM3914, but any help here is highly appreciated :) Also, I'm not sure how the difference between the LM3914 and LM3916 has (if at all) an impact on the project. I think I can use the LM3914 or LM3916 to apply a technique similiar to the LED Cube's where you don' t need a lot of pins to switch on/off individual led's. I have not found orange ones, so I'll go with red.ДЄnd that's where the questions already start. I might even hook up a small speaker and an amp (already build that stuff, should be easy to include). I want to build a knight-rider style Voicebox using 6x 10 segment LED graph bars which react to a soundsource (pretty much like a simple VU meter really). I know bits and stuff here and there and am able to put together and code some very basic stuff, but I decided to work on a (hopefully) simple project I want to keep rather than use for a day and get rid of again almost immediately ) I would still consider myself a complete newbie though since I never deeply dived into the world of electronics. I've been playing around with an Arduino Uno since quite a while now, hacked a couple of toys to make useless but fun stuff. This is my first post here, so I'm quickly going to introduce myself :)
