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 ...

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 … ...

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 ...
