Learn to use OTA (Over-The-Air) updates with the ESP32! Update your code without using a USB cable.
Today I wil show you three different OTA update methods that you can use with the ESP32.
ESP32 OTA (Over The Air) Updates
ESP32 Low-Power Modes
The ESP32 is a power-hungry beast, consuming up to 240 mA when the Wi-Fi is used. Thus makes running your ESP32 projects on batteries difficult.
Today we will learn ho we to use the ESP32s four Low-Power modes to reduce current consumption and increase battery life.
Using Ethernet with ESP32
Hook an ESP32 to your Local Area Network using Ethernet – this guide shows you how. We’ll Build a simple Web Server, and a PoE Camera that powers itself from an Ethernet cable.
Ethernet has a lot of advantages over WiFi, this article wil show you how to maximize your ESP32’s network performance.
MicroPythonOS – Android-like OS for Microcontrollers
Today we are taking a look at an operating system for the ESP32 – yes, an operating system for a microcontroller!
MicroPythonOS is an Android-like operating system for the ESP32. Today I’ll show you how to install it, use it, and build your own apps for it.
ESP32 Selection Guide – 2026
Here it is, the 2026 ESP32 Selection Guide! In this article you’ll learn about the (eleven) different variants of the ESP32 and how to select the best one for your application.
We’ll also look at some popular ESP32 boards to help you make the correct choice
Working with the Adafruit I2C Rotary Encoder
Rotary Encoders are so useful, but they can be hard to work with. Enter the Adafruit I2C Seesaw Rotary Encoder! This encoder uses an I2C bus, making interfacing it with a microcontroller very simple.
We will learn how the encoder works, then we’ll use it to build a Menu System and a fun toy – an Etch-a-Sketch!
Seeeduino XIAO ESP32-C5
Today we wil examine the exciting new Seeeduino XIAO ESP32-C5 board, the first XIAO board that supports 5 GHz Wi-Fi!
We wil see how the board works,and how to use it for communications and in low-power mode. We wil also build a Dual-Channel WiFi Analyzer with a Liquid Crystal Display!
Meet the Seeeduino XIAO Family
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).
WLED – Getting Started with ESP32
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.
TMP117 Precision Temperature Sensor
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.
