LED Audio MeterSeptember 21, 2012

Two weeks ago I received some MAX7219 samples from Maxim. So this past labor day weekend was the perfect opportunity to try one out. I started out by assembling another Atmega Lite from Gizmoz USA.
I have three of them, of which this is the second to use. My friend bought me two and I bought another one while I was visiting Portland, OR last year. These are great, cheap and breadboard usable, or good to embed in a project like I have done with my Smart Outlet. Plus you can use the Arduino bootloader.
So the first thing was to get one LED to light up, which I thought would be easy. Ha! Here are a picture with the Analog Sound Sensor, you can watch more pictures and a video on my blog, www.mobilewill.us.
