https://learn.sparkfun.com/tutorials/fingerprint-scanner-gt-521fxx-hookup-guide Hardware Overview Features The GT-521F32 and GT-521F52 have a lot in common with the previous models. They have the same protocol commands and packet structure. Code that was implemented for previous models should be functionally the same. The fingerprint scanner has the ability to: Enroll a Fingerprint Identify a Fingerprint Capable of 360° Recognition However, there are a few differences in the boards. These include: Different Board Layout 4x Mounting Holes 2x JST SH Connectors Touch Interface One significant difference to keep in mind when integrating the fingerprint scanner in a project is the number of fingerprints that the device can hold. The GT-521F32 costs less but it can hold only 200 fingerprints. The GT-521F52 is slightly more expensive but it can hold 3000 fingerprints. Technical Specs GT-521F32 / GT-521F52 CPU

The Raspberry Pi computer is a great tool for creating all kinds of interesting DIY projects and computer-powered builds. Whether it be used as a media center, web server, gaming console, or simply a computer, there are countless reasons why you might need a particular program or script to automatically startup when the Raspberry Pi desktop loads. While there are as many ways to run scripts at startup as there are uses for the Raspberry Pi, executing a script when the desktop environment boots is the easiest method with the most versatility. Configure your Raspberry Pi 1 Understand the requirements and how it works.  This method requires the PIXEL desktop environment with the latest version of the Raspbian Jessie operating system. It is achieved by editing an "autostart" file that runs commands at startup in the LXDE desktop environment, which is the framework the Raspberry Pi's PIXEL desktop is built on. This method is preferred in scenarios where: your script
