The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...

Simply put, unlike passive infrared sensors which detect objects by sensing changes in naturally emitted infrared, this active infrared close proximity sensor drives an infrared emitter to illuminate ...

Adding sensors to your Arduino opens up a whole new world of exciting projects. Here are some of the best sensors around.

[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 … ...
