August 2012, Page 14
In this month's Primer, we're going to continue our explorations of temperature measurement with PICAXE processors, but before we get to that, I want to give you an update on my "Freezer Alarm" project.

Introduction to the PICAXE-18M2 Processor
By
Ron Hackett
December 2010, Page 16
As promised, in this month’s Primer we’re going to take our first look at the new PICAXE-18M2 processor. If you read the brief “teaser” of new 18M2 features that I included in the previous installment, you already know that it’s an impressive processor, to say the least.
Implementing an ADC Keypad
By
Ron Hackett
October 2010, Page 67
This alternate approach only requires a single ADC input to decode a 12- or 16-key matrix keypad, so it’s suitable for use with any 08M-based project.
Introducing Tex and Rex: The IR Twins
By
Ron Hackett
August 2010, Page 14
In this month’s column, we’re going to re-visit the infrared realm, but this time we’re going to take a different approach and develop two very simple IR boards — each of which serves only one specific function. Rex will be our IR receiver and Tex will transmit IR signals to Rex.
Using the AxMate Power and Programming Adapter
By
Ron Hackett
June 2010, Page 52
In this month’s installment of the PICAXE Primer, we’re going to construct a simple “AxMate” adapter that provides all the necessary breadboard connections for powering and programming a PICAXE project.
Programming the MAX7219 LED Display Driver
By
Ron Hackett
April 2010, Page 16
This month, we’ll experiment with three different programs for our display and one for our 28X1 master processor. First, we’ll try out a simple program to count from 0 to 9999, and then we’ll throw in a little “zero-blanking” for good measure.

December 2009, Page 62
This time,we’re going to experiment with interfacing seven-segment LED displays with PICAXE processors.To explore the basic concepts involved, we’ll begin with the simplest case: interfacing a single-digit LED display with a 20M processor.
Using The AXE027 USB Programming Cable

Ron Hackett
October 2009, Page 67
This month's Primer we're going to take a first look at how to cope with the process of migrating from the serial to USB programming connections.
Programming Your Serialized LCD Display
By
Ron Hackett
August 2009, Page 15
This month we’re going to turn our attention to some of the details of programming the display. Specifically, we’ll investigate two of the most useful features of LCD displays: scrolling a long line of text across the relatively small width of the display and creating custom characters to enhance the functionality of the display.
Taming Unruly LCD’s: Part 2
By
Ron Hackett
June 2009, Page 67
The 14M is the perfect processor for this project. It has more than enough I/O lines and program memory for the task at hand and it’s cheap enough that you can construct two or three complete “serialized” LCDs for the price of one commercial display.
Taming Unruly LCDs: Part 1

Ron Hackett
April 2009, Page 56
In the previous installment of the PICAXE Primer, I said we would turn our attention toward interfacing our Master Processor with inexpensive LCD displays based on the Hitachi HD44780 controller
Implementing a serial data link with the IR multi-board

Ron Hackett
February 2009, Page 16
This month, we're going to resolve the problem of the missing keypresses that we had last time with our SIRC system and then move on to accomplishing our final goal for the IR Multi-Board:
Playing Music and Watching Lights
By
Ron Hackett
February 2008, Page 74
In the first installment of the PICAXE PrimeR, we took a look at the 08M’s music making capabilities and used the super simple “play” command to play “Rudolph the Red-Nosed Reindeer.” This month, we’ll expand our repertoire by exploring the “tune” command, which will enable us to play any tune we choose. As I mentioned last time, there are nearly 1,000 tunes available for free downloading at the Revolution Education website (www.rev-ed.co.uk/picaxe/)...
Getting Started With Stripboard Circuit Construction
By
Ron Hackett
April 2008, Page 88
If you have been reading the PICAXE Primer or any of my articles in Nuts & Volts and SERVO Magazine, you know by now that I am very partial to working with breadboard circuits. I think they are by far the fastest and most flexible approach to building and debugging a PICAXE-based circuit, or any small circuit for that matter. However, sooner or later you may want to construct a circuit that is more reliable and “permanent” than a breadboard circuit...
Good Intentions and “Faux” PC Boards
By
Ron Hackett
June 2008, Page 82
It’s funny how things sometimes get away from me. My original intention for this month’s column was to present an introduction to the many new and powerful features of the PICAXE-28X1 processor but, as I started to elaborate on the details of some of these features, it began to feel like information overload...
Build The PICAXE IR Multiboard
By
Ron Hackett
October 2008, Page 83
This month, we’re going to develop and test our first I/O device for use with the PICAXE-28X1: an 08M-based, multi-function infrared board capable of implementing the entire range of PICAXE IR communications.
Experimenting With The IR Multi-Board
