Enigma Cipher Machine story up at apcmag

The Arduino Uno microcontroller is a pretty impressive little number – so impressive, in fact, you can turn it into a fully-working Enigma Cipher Machine.
I know I’ve been banging on about this project a little lately, but I was pretty damn chuffed when it started working (it’s one of the most complicated pieces of code I’ve had the pleasure of putting together!).
Now, the full story has now gone up on the APC magazine website.
What’s cool about it… Read more

Software for the Arduino Enigma Cipher Machine

In the current August 2014 issue of APC Magazine, I’ve written about a functional-replica of an Enigma Cipher Machine that I’ve designed and built using an Arduino Uno microcontroller board.
But if you’re looking for the software, it’s on the APC magazine website but at in the August 2014 section.
Hopefully, it will be transferred to the regular Arduino page ( page shortly.
Sorry for the confusion.
The Arduino Enigma displays everything on a 16×2-LCD module shield and accepts… Read more

Turn an Arduino Uno into a digital audio recorder

One of the great things about Atmel’s ATMEGA328P microcontroller that powers the Arduino Uno boards is the sheer versatility of the chip. It might only clock in at 16MHz and process data in 8-bit chunks, but it has so many practical real-world interface options that helps it punch well above its weight.
My favourite part of the chip is the ADC or ‘analog to digital converter’. By rights, it’s only a 10-bit ADC and only has a rated sample rate… Read more

What has happened to the Arduino Zero?

It was announced with considerable fanfare back in May 2014, but since then, the Arduino team has been all but silent on the upcoming replacement for its popular Arduino Uno microcontroller board.
The new board, dubbed Arduino Zero, could well be a gamechanger for the DIY/maker community with its considerably up-scaled processing and storage power.
Rather than stick with Atmel’s 8-bit ATMEGA series used on the Uno or even the SAM3X8E 32-bit Cortex M3 controller found on the Arduino Due,… Read more

Build your own Digital Audio Recorder from #arduino

The first part of my Digital Audio Recorder project has just hit the APC mag website.
I had heaps of fun putting this project together – and now you can do it yourself. The story includes all you need to know to build it, including the software that turns the Arduino Uno into a digital recorder.
The project records analog audio via a 3.5mm stereo panel socket to a MicroSD card in WAV format, playable on any WAV-compatible device or… Read more
