ESP32 Boards Manager 3 for the Arduino IDE offers a significant improvement over previous versions. But that improvement comes at a cost – a lot of older ESP32 code will no longer compile.
Today we wil examine the new features of Boards Manager 3 and see how to convert our older code.

Digital Potentiometers, or “DigiPots”, are exactly what you think they are – potentiometers whose wiper position is set using a digital signal instead of a mechanical shaft or slider.
Today we will see how to use Digital Potentiometers and we’ll build a couple of projects. We’ll build a remote-controlled audio volume system and a variable power supply whose output voltage can be set with a web-based interface.

Looking for a power supply for your next project? How about one that can deliver up to 20 volt’s at 5 amps?
USB-PD is a technology that permits USB power supplies and chargers to deliver multiple voltages and currents. Today we wil learn how to use USB-PD in our projects.

Meet the Alvik, a tiny yet powerful robot from Arduino. Alvik may be small, but it packs some advanced sensors and can be programmed using MicroPython or C++.
Let’s take a close look at the Alvik and learn how to write code for it. We’ll also see how we can add servo motors and I2C devices to expand our robots capabilities.

The Arduino IoT Cloud has had many exciting updates since we last examined it, so many that in 2024 it doesn’t even look the same! With a wealth of boards to connect to, and new features like Triggers, it’s time we took another look at the Arduino IoT Cloud.
Follow along for a detailed guide, suitable for makers of all levels!

Diodes are the oldest and most elementary semiconductor. They are also among the most useful, and there are a variety of diodes to do everything from convert AC to DC to detecting radio waves and to producing light.
Today we wil take a look at diodes. We’ll see how they work, and how to use them.
