We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

[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 ...

Instructables member AGBarber has created a fantastic measuring tool in the form of a Arduino powered digital tape measure called the DMW. Which cannot only measure distances on surfaces but can also ...
