If you're on the hunt for the perfect board, then you've probably come across the Uno and Nano. They're two of the most frequently used Arduino variations, but they serve different purposes.

In fact, it's only slightly larger than Arduino's smallest board, the Nano, at 51 mm x 21 mm. Both boards are excellent options for circuit building and prototyping, but are there any differences ...

Although a “CommsLink” module providing an RS-232 port was available back in the day, it’s become hard to find, inspiring [James] to design a completely new module based on an Arduino Nano.

The micro-lab uses the Berthelot reaction, which detects ammonia through a color change. Instead of the traditional toxic ...

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 ...
