Doorbells are the 20th century version of today's perpetually-interrupting cell phone. There you are, cooking a delicious dinner or reading a nice book when the doorbell rudely goes off in your ear. Sure, you're glad to see whoever is at the door, but interruptions that chime can be so obnoxious. Needless to say, I do not have a doorbell.   The problem with the knocking system is that I usually can't hear when someone knocks from my lab. I depend on Penny the Dog to alert me when someone i ...
Arduino has a pretty good footing as the household name for beginners to get into electronics.  Especially when it comes to that critical first task of blinking an LED, no other manufacturer makes it easier.  Thanks to the power of today's microcontrollers, there is enough functionality in an Arduino to take a beginner and turn him or her into a pretty dangerous designer.   But what happens when the newly-accomplished engineer wants to expand beyond the hardware provided by the ...
Have you put together an Arduino-based circuit and looking to nicely (but easily) document it?  Or perhaps you're looking to create an Arduino Shield with EAGLE and want to start with the correct dimensions of the headers.  Element14 has come to the rescue with the Arduino library of EAGLE parts for exactly that.  There are two types of components in this library: the standard version with a PCB footprint showing the key connections and the 'EXT version which has no PCB footprint. ...
Chris Gammell is an accomplished Electrical Engineer who currently works in electronics design by day and talks his head off about electronics by night to anyone that'll listen.  He co-hosts The Amp Hour podcast, writes on ChrisGammell.com, tweets more than most engineers, and is on the cusp of launching a new way to learn electronics: Contextual Electronics.  I've known him from our time at Case Western Reserve University and two different jobs, and was able to catch up with him for a ...
  Key Specs: There has been a lot of anticipation for the arrival of the Due, and with good reason.  The board's capabilities far exceed other Arduino boards and does a good job rounding out the product line.  Here are some key specs that Arduino proudly publishes on the product's page: $49 price point 32-bit processor at up to 84MHz 54 Digital I/O pins, 12 ADC pins, and 2 ADC pins 2 USB-micro ports: one for programming the Due, the other for interfacing with peripherals ...
