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
Column: PICAXE Primer

Taming Unruly LCD’s: Part 2
Column: PICAXE Primer
June 2009
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.

Playing Music and Watching Lights
Column: PICAXE Primer
February 2008
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 ([url=http://www.rev-ed.co.uk/picaxe/]http://www.rev-ed.co.uk/picaxe/[/url])...

Getting Started With Stripboard Circuit Construction
Column: PICAXE Primer
April 2008
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
Column: PICAXE Primer
June 2008
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...

Getting Started with the PICAXE-28X1 Microcontroller
Column: Getting Started With PICS
August 2008
In essence, the PICAXE-28X1 is like a 28X on steroids. It’s pin-for-pin compatible with the 28X and all the 28X commands will function correctly on a 28X1. In other words, if you have an existing 28X circuit, it will function exactly the same with a 28X1 installed. This is a good thing, because Revolution Education considers the 28X to be obsolete and has discontinued it. Amazingly, the new 28X1 is about the same price as the old 28X...

Build The PICAXE IR Multiboard
Column: PICAXE Primer
October 2008
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.
