An RGB LED module is a versatile lighting component that can produce millions of colours by mixing red, green, and blue light. The RGB LED module used in this ESP32-S3 Box-3 Arduino programming ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

Arduino has certainly made its mark in the world of DIY electronics, providing an accessible platform for a wide range of creative and interactive projects. Known for its user-friendly hardware and ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

After a major water leak flooded my home, I realized alerts alone weren’t sufficient—I needed automatic shutoff. This project combines a hacked Gröhe Guard system, an Arduino Nano, an ESP32, and the ...

It’s probably not much of a stretch to say that many of us have taken on a project or two that were little more than thinly veiled excuses to add a new tool or piece of gear to our arsenal. There’s ...

The company was early into adding phase-locked loop clock multipliers to give the PWM machinery something faster than the processor clock to work with. Arduino offers a simple framework to programme ...
