In order to facillitate the system you see outlined below and detailed on the Wifi Scanner Project Page.
Programming an Arduino was needed. You can view the code for that project on GitHub
I had an idea to create a suitcase sized wardriving computer, that I could place on my E-Bike. A Wardriving computer would consist of a arudino controlled servo motor mount for a small wifi dish antenna. The Signals from which would be passed into a Raspberry Pi to be analyzed and logged by Kali Linux.
So I sent to work on formulating the idea in my head and writing some of the schematics down on paper. Purchasing Components, and Testing Board Layouts for Physical Fit.
