There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

2016 was a great year for Open Hardware. The Open Source Hardware Association released their certification program, and late in the year, a few silicon wizards met in Mountain View to show off the ...

In this article, I'll be explaining the basics of how microcontrollers work, physically and virtually. First off, microcontrollers are no simple thing, so don't be discouraged if you find it ...

The Arduino 101 equipped with Intel's Curie module integrates a 6-axis gyro/accelerometer and Bluetooth, which sets it apart from the rest of the Arduino line up. What the heck is an Arduino? Simply ...

There are many reasons to build your own Arduino circuit on a protoboard or a custom-designed printed circuit board. At the heart of the Arduino platform is an AVR microcontroller, in usual way you ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...
