The Turtle Bot is one of the classics for Arduino tinkering. The YouTuber UncleStem has built it seven times larger – and it works. The hobbyist and YouTuber UncleStem has built the often-replicated ...

When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects, you might ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

In a nutshell: For the growing community of at-home hardware tinkerers, a new project offers a striking example of how low-cost components and open-source collaboration are closing the gap between ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...

Like Ars Senior Technology Editor Lee Hutchinson, I have a garage. The door on that garage is opened and closed by a device made by a company that, as with Lee’s, offers you a way to open and close it ...
