This is a project from [Mirel] who built the system around a Arduino Mega 2560 and antipodal Vivaldi antennas, a type of directional antenna.

Stepper motors are mostly used for precise motion control of structures or axes for a distance. But what happens if we want to control time? We can answer this question with the bare motor rotation, ...

The idea early on was to leverage existing Arduino libraries to connect with a standard USB mouse, specifically, the hardware would take the form of an Arduino Mega 2560 with a USB Host Shield.

Other official builds include the Arduino Nano, designed to take up as little room as possible, and the Arduino Mega which features significantly more inputs and outputs than its cousin.

The Arduino Mega 2560 is at the heart of this project, chosen for its ample I/O capabilities. With 54 digital I/O pins and 16 analog inputs, it can handle a multitude of controls simultaneously.

I'm taking the liberty of starting a new thread for Arduino projects, as I couldn't find one dedicated to this, and figure that there may be a few people around here who do this sort of thing. If ...

It's of course backwards compatible with existing Arduino add-ons, but sets itself apart with a new USB controller with lower latency and driver-free operation on Mac and Linux.

While a Raspberry Pi is a full-fledged computer that can do more complex things than an Arduino microcontroller, it's not the best choice for every project.

If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?
