[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.

Apart from understanding the Arduino's code language, one of the most confusing parts about the platform ... there are two options: a Nano and a Micro. They look like the same board to the ...

An Arduino Nano is charged with running the show, capturing audio via its analog-to-digital converter. A sensitivity pot enables the input level to be set appropriately. From there, a Fast Fourier ...
