Once you learn how to read Morse code, you might want to teach your Arduino to understand it, too. You can see the project in operation in the video below. The device acts like an old commercial model, the Datong D70, although it can optionally accept an LCD screen, something the D70 didn’t have. wanted a device to generate practice code, so he built it around an Arduino. The state of the art today employs a computer to randomly generate practice text.

In the old days, you usually learned Morse code from an experienced sender, by listening to the radio, or from an audio tape. If you know Morse code, you could privately talk to a concealed computer on just two I/O lines. Finally, Morse code is a very simple way to do covert communications. Morse code can be sent using low power, equipment built from simple materials or even using mirrors or flashlights. Another reason is that Morse code can often get through when other human-readable schemes fail. First, some people actually enjoy it either for the nostalgia or the challenge of it. There are, however, at least three reasons you might want to learn it anyway.

You don’t need it for a ham license anymore. You may wonder why anyone would want to learn Morse code. Even if you are buying just one, you should be able to find the device for under $6.Ĭontinue reading “ARMing A Breadboard - Everyone Should Program An ARM” → Posted in ARM, Featured, Slider Tagged arm, breadboard, lpc1114, mbed, prototyping The chip will work with mbed or other ARM tools and after prototyping, you can always move to a surface mount device for production, if you like. It does require 3.3V, but it is 5V tolerant on digital inputs (and, of course, a 3.3V output is usually fine for driving a 5V input). Unlike most other ARM processors, this one comes in a 28 pin DIP package and works great on a breadboard. One solution that addresses most, if not all, of these concerns is the LPC1114FN28 processor.
Even if you don’t mind using a development board, you may want to use the IC directly in a final version of a project and some people still prefer working with through hole components. But in some situations–for example, in classrooms–it is very attractive to have a chip that is directly mountable on a common breadboard. Of course, builders today are getting pretty used to surface mount devices and you can also get evaluation boards pretty cheaply, too. But perhaps the largest hurdle is that most of the chips are surface mount devices.
There was a time when the toolchain was difficult to set up, although this is largely not a problem anymore. For one thing, most ARM chips use 3.3V I/O instead of the traditional 5V levels (there are exceptions, like the Kinetis E). Having a 32-bit processor with lots of memory running at 40 or 50 MIPS is a game changer compared to, say, a traditional Arduino (and, yes, the Arduino Due and Zero are ARM-based, so you can still stay with Arduino, if that’s what you want).Ī few things might inhibit an Arduino, AVR, or PIC user from making the leap. Of course, we do see some, but the volume isn’t what I’d expect given that low-level ARM chips are cheap, capable, low power, and readily available. I’m always a little surprised that we don’t see more ARM-based projects.
