Cap’n ArrDrownHo! is the lovechild of Ardweeny and Boarduino and he’s here to commandeer your AVR ships. ArrDrownHo! inherits pros of both and cons of neither. Pick up an AVR chip and start prototyping instantly on a breadboard! Want to replace that costly Arduino in your project with a cheap AVR, but don’t know how? Use the simple plug-and-play […]

The Knock Box is a power strip with superpowers – it turns on your lamp whenever you knock on your nightstand. You get two outlets, individually controlled by knock-knock-knocking on a nearby hard surface. It’s great for hitting the lights when it’s pitch dark, but if an appliance can plug into the wall, you can toggle it!

The Pi is a fine little computer board, though not nearly as good as the Arduino when it comes to I/O capabilities. The beautifully-engineered Gertboard is a plug-in add-on that neatly overcomes this deficiency by giving the Pi access to an ATMega328, but it’s a very complex and expensive solution. An alternative would be to interface

I learned that one of my nieces had an interest in programming. She was working with robotics at high school and has a summer internship where they had Arduinos. I think she was able to borrow an Arduino to experiment with at home but every Maker knows that is not the same as having a

Just as you can concatenate Strings with other data objects using the StringAdditionOperator, you can also use the += operator and the cconcat() method to append things to Strings. The += operator and the concat() method work the same way, it’s just a matter of which style you prefer. The two examples below illustrate both,

Intro: If you’ve got an Arduino Uno and want to start duplicating projects without having to buy an Uno every time… get ready to live! This instructable will show you how to move your projects (that do not require serial communication) onto a breadboard for prototyping or expansion. If you’re looking for a more permanent

A Smapler is a circuit dedicated to the production of generative sound created by David Cuartielles and Ino Schlaucher from BlushingBoy.org. The Smapler v0002 -aka Singapore edition- is nothing but an Arduino shield to be used for playing funky stereo sounds. As an extra add-on the Smapler v0002 circuit includes a PS2 connector for you
Mounting a Smapler v0002 step by step Continue Reading
The ‘Poduino Case’. A protective case for your Arduino (with breadboard work area): I just received my Arduino Duemilanove and breadboard today. After some careful thought, I realized there is no way this thing could possibly survive daily life on my desk. I saw some great Instructables on plastic cases, and even one that used
Every job has it’s routine. I am a software developer who works with a Git/Maven based workspace everyday. So when I start working, my daily routine is to update and build my local workspace, pulling changes from GitHub, execute a maven build and execute the updated software. Usually I get my first coffee after that,

Metal oxide semiconductor field effect transistor (MOSFET) is a semiconductor device widely used for switching applications and amplifying electronic signals. While the facility to determine the type and pin configuration of bipolar junction transistors (BJTs) are available in digital multimeters (DMMs) used in the laboratory, most DMMs do not provide such features for MOSFETs. This
