Come meet the XIAO family! Today we wil take a look at all of the members of the Seeeduino XIAO microcontroller family. And there are over a dozen of them!
We wil check out their specs and then create three very different projects that use the same circuit (but different XIAO boards).

Come meet the new Arduino Nano R4, the latest member of the growing Nano family.
Today we’ll check out the Nano R4 and examine some of its more interesting features, like the DAC, Real Time Clock and Operational Amplifier
A complete guide to using DC servo motors with microcontrollers like Arduino and ESP32.
Learn how servos work, how to code for them and get some troubleshooting tips.
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!
The Arduino GIGA Display Shield is a powerful TFT display with integrated IMU, microphone and RGB LED. This capacitive touchscreen display even has a connector for a camera.
Today we will see how to use this display and its advanced features to build powerful user interfaces.
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.
The latest member of the growing Arduino Nano family is the Arduino Nano ESP32. It’s actually the first Arduino to use an ESP32 as its main processor.
Today we will look at this new board, and we’ll also run a few experiments with it.
We will configure it as an HID (i.e. mouse), use it with MicroPython and connect it to the Arduino IoT Cloud.
After 12 years, Arduino has released the latest edition of the classic Arduino Uno. Actually, it’s two boards, the Arduino Uno R4 Minima and the Arduino Uno R4 WiFi.
These boards are 5-volt logic devices and are physically compatible with the older Arduino Uno R3 boards, preserving your investment in shields and prototyping equipment. In addition, they offer many new features, several of which we’ll examine today.
