Programming the Raspberry Pi with Perl
Programming the Raspberry Pi with Perl
About the Book
Have you ever wondered how to make your garage door open over the Internet? Or maybe do facial recognition in real time from a camera? Log the temperature of a room? It's easier than you'd think, and Perl can help you do it.
Meant for current Perl programmers who want to expand into hardware programming. The examples are kept simple, so knowledgeable programmers in any language should be able to follow along.
