I am building a Radio Spectrum Analyzer which measures signal strenght in the 2.4GHz band, using a CYWM6935 module and Atmega 328 MCU. I want to set it up in several steps:

Atmega328 on a breadboard

There are quite a few good "Arduino on a breadboard" tutorials out there. I suggest you take a look at

These were the components I bought (or borrowerd here on the nurdpspace):

Connecting the CYWM6935

Programming the Atmega328

Creating desktop software for visualization

I chose to create a Java GUI using JFreeChart to read the data from the Arduino using an FTDI cable on a serial port (or actually USB) and visualize that in the GUI. The program can be found on Github.

This is a screenshot from the app. It allows you to reset the maxima by clicking the button.
