ESP32 Boards Manager 3 – Updating Your Old Code
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.
Using Digital Potentiometers to build Unique Projects
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.
USB-PD – Power for Your Projects
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.
Arduino Alvik Robot
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.
Arduino Iot Cloud 2024 – Fundamentals
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 – A Practical Guide
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.
ESP32 Guide 2024 – Choosing and Using an ESP32
Since its introduction in 2016, the ESP32 has become one of the most popular microcontrollers in the world. It has now grown from a single ESP8266 replacement chip into a complete line of powerful microcontrollers and communications modules.
Today we will look at the status of the ESP32 as of January 2024. We will also take a look at a new Alpha of the ESP Boards Manager for the Arduino IDE.
IR Remotes Revisited – 2023
It’s time we took a fresh look at infrared remote controls, so here is everything you need to know about using IR remote controls with microcontrollers.
Learn how to receive, decode and send IR signals, including ones from those hard-to-decode remotes like air conditioners.
Examples with both an Arduino and ESP32.
