I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ...

You'll need an Arduino along with a bunch of various sensors to get the project rolling, and once it's all set up you'll have a simple, but cheap system to monitor your home.

The chip comprises an analog temperature sensor that converts temperature to analog voltage. Unlike resistive sensors, this linear active thermistor chip does not require an additional signal- ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The … ...

An index needs to be created to store data from the Arduino boards, including temperature values, device position using geo-location, a device identifier name, and a timestamp.

John Boxall, author of the new book Arduino Workshop, shares a few of the projects from his book on how to get started with the microcontroller. (Click the links to see PDFs of the complete ...
