Here's your next round of cool reads.
It's probably worth mentioning that when we introduced a new Q&A section last week, readers were emailing with questions and comments probably not realizing the material was from past columns, all the way back to the beginning (over a decade). Since the original Q&A author passed away a number of years ago, we obviously can't forward anything to him to weigh in on. So, we added Disqus commenting to the section so you can comment, rant, ask questions, criticize, correct, or whatever. So feel free to start or chime in on the discussion. After all, that's what makes it interesting.
And thanks once again to the great folks over at M.E. Labs!
That's it, Enjoy!

Happy Birthday Internet!
Switching to the TCP/IP networking standard radically transformed the Internet from a network that connected military and university mainframes to the sprawling "information superhighway" that reaches into hundreds of millions of homes, businesses, and schools, and has radically transformed the lives of its users.

Digitally Programmable Potentiometer (DPP) Basics
The digitally-programmable potentiometer (DPP) is a mixed signal, system-level control device performing a component-level function. The potentiometer adds variability to the analog circuit, while the digital controls add programmability. The DPP brings the high speed, programming, computation, and control of a processor to the variation of the potentiometer in a wide array of analog applications.

Learning Systems for PICs
This is an educational learning system
- not just another experimenter board
- for all levels of programming from beginner to expert.
Learn the fundamental concepts of programming, from plain-English descriptions of software tools to concepts including program flow, loops, coding techniques, binary manipulation, device-to-device communication, user-interface design, and more.
14 Lessons use a building-block approach to teach you incrementally, from a six-line program to a working user-interface.
Tutorial assumes no prior knowledge of programming.
All necessary hardware and software included, all you need is a computer with a standard USB port.

Smiley's Workshop 34
C Programming * Hardware * Projects
Our last episode provided a convenient way to hook up a serial connection and provide a power supply for use in electronics prototyping on a solderless breadboard. Now, let's use that for general-purpose I/O to read switches and light LEDs. Then, we'll use a seven-segment LED to make the "World's Smallest Moving Message Sign," then finally we'll create an Arduino compatible prototype on a breadboard.

Security Electronics Systems And Circuits - Part 5
Optoelectronic security circuits - which respond to either visible or invisible (usually infrared) light levels - come in three (3) basic types. Last time, we covered circuits of the visible light type. This time, we'll tackle IR 'light-beam' and PIR circuits.

Programming the Propeller with Spin:
A Beginner's Guide to Parallel Processing
It's been said that:
Once you learn to use the Propeller in its parallel processing environment, you will be hard pressed to ever again use a conventional processor for the kind of tasks small microcontrollers are designed for.
This book covers Propeller hardware and software setup, memory, and the Spin language. Step-by-step projects give you hands-on experience as you learn how to:
- Use Propeller I/O techniques with extensive Spin code examples
- Display numbers with seven-segment displays
- Create accurate, controlled pulse sequences
- Add a 16 character by two line LCD display
- Control R/C hobby servos
- Use motor amplifiers to control small motors
- Run a bipolar stepper motor
- Build a gravity sensor-based auto-leveling table
- Run DC motors with incremental encoders
- Run small AC motors
