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.
Today we are working with the TMP117, a precision temperature sensor with an accuracy within 0.1 degrees Celsius.
We’ll see how this sensor, on a module from Adafruit, can be easily connected to a microcontroller to build a super-accurate thermometer. We’ll even put together a WiFi thermometer with an OLED display.

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.
Bluetooth Classic and Bluetooth Low Energy (BLE) and short-range communications systems that connect computers, mobile devices, peripherals and sensors. You probably have several Bluetooth devices in your home, and with the ESP32 you can connect to all of them.
The ESP32 is Bluetooth-capable, but not every ESP32 wil work with every version of Bluetooth.
Join me today to learn all about Bluetooth and how to work with it on the ESP32.
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 Seeeduino XIAO ESP32s3 Sense board is a super-tiny ESP32 camera board that includes a microphone, MicroSD card, USB-C connector and a battery charger.
Today we will take a look at this tiny microcontroller and put it through the paces. We’ll also upgrade its camera and build a camera that also records sound
