The analog approach has nothing to do with an Arduino you use the LM3914 or LM3916 (which is an actual "VU" meter variant) to drive the LEDs according to your audio input level. You can approach it in either of two ways analog, or digital. OK then, you have a decision to make here.ĭoes an Arduino have anything at all to do with this project? So hopefully I'll be able to put this together with the help of you guys :)

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).
Knight rider kitt voice box how to#
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? )Īnother 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.Īnd 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 :)
