HIGH PRECISION ANALOG IO WITH DIGITAL PINS

Reading the temperature of your environment is pretty easy right? A quick search suggests the utterly ubiquitous DHT11, which speaks a well documented protocol and has libraries for every conceivable microcontroller and platform. Plug that into your Arduino and boom, temperature (and humidity!) readings. But the simple solution doesn’t hit every need, sometimes things need to get more esoteric. For years we ...

USE A DIGITAL KEY TO DETER LOCKPICKING

Spending an hour or two around any consumer-level padlock or house deadbolt lock with a simple lockpicking kit will typically instil a good amount of panic and concern about security. While it’s true that any lock can be defeated, it’s almost comically easy to pick basic locks like this. So, if you’re looking for a level of security that can’t be defeated in two minutes with a tiny piece of metal, you might ...

FPGAs For MCU Guys

A little while ago, it struck me that I was getting tired of explaining what FPGAs are and how they work their magic to those of my chums who -- thus far -- have worked only with microcontrollers (MCUs), so I decided to write a three-part mini-series of articles to offer as an introduction. As I said in the first column: A lot of my friends are highly experienced embedded design engineers, but they come fro ...
