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.
Learn how to use both 7-segment and dot-matrix LED displays with an Arduino.
We will be working with both single and multiple display units, in a variety of configurations.
LEDs are by no means dead, they are still a great choice for a number of applications. Add one to your next Arduino project.
In addition, we will build an Arduino OLED Temperature and Humidity Meter using an OLED and an I2C temperature and humidity sensor.
RGB (Red-Green-Blue) LEDs are versatile devices that can add color and functionality to your Arduino projects.
In this article we’ll examine the different types or RGB LEDs available to experimenters and see how to best use them with an Arduino. It promises to be a very colorful read!
Here is a list of the best sites on the Internet for learning electronics, no matter what level of expertise you have.
Best of all, every resource on this list is free!
Today we will look at some useful and unique tools for the ESP32 microcontroller. All of these tools run online in your web browser, no software installation required.
We will explore Diagnostic tools, Firmware Installers, Software Installers and even a few Online IDEs. Come check them out!
Today we wil look at rapid prototyping systems, wiring systems that allow you to quickly hook up common electronic components, modules and microcontrollers.
We will take a look at three of the most popular systems – Qwiic, Grove and STEMMA. We’ll see how they work, and how they can speed up the development process and eliminate wiring errors
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.
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
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!
