[HamBrewers] Audio spectrum scope with an Arduino

 

Dear HAM Brewers,

Here is an article I wrote about a small program to turn an Arduino + cheap 16x2 LCD in an Audio spectrum scope.
The audio bandwidth displayed is from 150Hz to 3150Hz so useful for HAM radio operators.
The program is free of use.
The article is in french but all the source code comments are in english. The automatic translation can help you to understand the article...

I am planning to offer a kit for this circuit soon.
The kit will be "no soldering" and will include an Arduino board, a 16x2 LCD and a back-plane to connect the other parts on it.
Price is expected under 30$ plus shipping...

73,
Yan.
