What are your recommendations for an easy to do audio spectrum analyzer project using an LCD? I've searched the forum and found a few varieties of LCD spectrum analyzers but I could use some guidance as to which to chose as my first project of this type. I'm looking to use a simple LCD like a 16x2 or a 20x4, something along those lines. I'm a bit more concerned with speed than accuracy as I'd be happy with something that looks cool. Another concern is that I'd prefer something that runs on an arduino UNO s that's the arduino I have.
What are your recommendations? Your advise is highly appreciated, thank you.
A more traditional display would use bar graph LEDs. If you search for "led bar graph" on eBay, you'll find that you can get them for about $2/each. Especially if you buy 10 at a time. A little more for the tricolor displays. You'll need to use some type of driver to provide the required current, Using Maxim 7219/7221 LED drivers is one approach.
Thank you for your replies, The reason I want to use a 16x2 display is that it's what I'm most familiar with at the moment. Also I'd like to display text on it once I'm a bit more knowledgeable as to how it works. Basically I'm looking for a project I can build on rather than one that will have only one purpose. Ultimately maybe take what I learn there and build an mp3 player or something like that.
Here's a couple videos showing pretty much exactly what I want to do.
I'm not looking for anything that will show something super accurate but at least show a cool bar graph to go along with the audio. I'm a newbie so I'll definitely need some help!
