Want to build n electronic compass or a guidance system for a robot? Adafruit’s LSM303AGR module is the perfect component for you.
Today we wil look at this versatile module and perform experiments with it. We wil also see how to calibrate it, and we wil indeed build a simple compass with an OLED display.
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).
Learn to setup and use WLED, the amazing ESP32-based product for controlling every type of LED strip. We will see how WLED works, how to choose LED strip lights and how to safely wire everything up.
We wil also hookup a microphone and use Audio Reactive, to control our LEDs with sound.
Non-volatile Storage is memory that keeps its data without power. Pretty useful for saving configuration settings and web data.
Today we will examine four types of non-removable NV Storage – Internal Flash, External EEPROM, SPI NOR Flash and FRAM. We’ll see how they work, what advantages (and disadvantages) they have and how to use them with an ESP32.

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.
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.
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.
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.
