Python for Secret Agents - Volume II - Second Edition

By: Steven F. Lott, Steven F. Lott

Overview of this book

Python is easy to learn and extensible programming language that allows any manner of secret agent to work with a variety of data. Agents from beginners to seasoned veterans will benefit from Python's simplicity and sophistication. The standard library provides numerous packages that move beyond simple beginner missions. The Python ecosystem of related packages and libraries supports deep information processing. This book will guide you through the process of upgrading your Python-based toolset for intelligence gathering, analysis, and communication. You'll explore the ways Python is used to analyze web logs to discover the trails of activities that can be found in web and database servers. We'll also look at how we can use Python to discover details of the social network by looking at the data available from social networking websites. Finally, you'll see how to extract history from PDF files, which opens up new sources of data, and you’ll learn about the ways you can gather data using an Arduino-based sensor device.

Collecting analog data

Our goal is to gather data from an analog range sensor. This device must be connected to one of the analog input pins. We also need to connect it to power and ground pins. According to the documentation for the GP2Y0A21YK, the sensor has three connections: Vo, GND, and Vcc. With the sensor pointing up, the left-most pin is generally Vo, the output that will connect to Arduino A0 to provide analog input. The center pin is ground, which connects to one of the Arduino GND connections. The right-most pin will be Vcc, the supply voltage that will connect to the +5 V pin on the Arduino.

Many of these devices have a little JST three-wire socket. We can buy a nice little JST three-wire jumper. The color coding of the wires on the jumper may not fit our expectations very well. We may wind up with Vcc on the black-colored wire (black is often used for ground) and the ground connection on the red-colored wire (red is often used for +5V.)

If we connect things up wrong, there will...
