We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [Rick’s] ...

A keypad is one of the most commonly used input devices in microprocessor applications. In a standard keypad wired as an X-Y switch matrix, normally-open switches connect a row to a column when ...

The annual Consumer Electronics Show is in session, which means thousands of people have descended on Las Vegas to stare at next year's dust-gathering trash. Maybe you can do better. Maybe it's time ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

The readability of your code can make the difference between your project being a joy to work on, or an absolute headache. This goes double when collaborating with others. Having easily parsed code ...

There’s one big problem with the Arduino development environment, also known as an IDE: There’s no network hookup to directly share and browse code you’re writing for these little microcontrollers. It ...

The official Arduino IDE is a dour piece of software designed for uploading code to the ubiquitous and super-cool micro controller. It is a standalone, non-networked app that isn’t very pretty to look ...
