LoRa is a Long Range radio system that is inexpensive and free to use. You can achieve great distances with a simple wire antenna, and LoRa is very easy to use.
Today we will see how LoRa works and how we can use LoRa modules to communicate between Arduino, ESP32 and Raspberry Pi Pico boards.
We’ll also build a data-gathering system that you can easily expand upon.
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.
Learn to use seven different DC motor drivers with an Arduino Uno.
We’ll see how to put these to use with motors of all sizes, and of course we have hookup diagrams and code samples!
Measure the quality of the air you are breathing using a variety of sensors, an Arduino and an ESP32.
In this article I’ll discuss air quality parameters and show you how to use several popular sensors to measure the gases and particulate matter in the air
Get the best of both worlds by building a dual-boot workstation!
I’ll show you how to take a “bare-bones” workstation and install both Microsoft Windows 11 and Ubuntu Linux 22.04.
Linear DC Power supplies are no longer as common as switching supplies, but they are still a good choice for many applications.
Today we will learn how linear power supplies work, how they differ from switching power supplies, and how to use voltage regulator modules.
We will then construct a DC Power Supply suitable for use on the workbench.
The GC9A01 is a circular LCD module that is ideal for instrumentation and other cool display applications.
In this article, we will learn how to use this display with an Arduino Uno and an ESP32.
The I2S protocol is not a misspelling of I2C, it is a protocol for controlling digital audio.
Today we will use the I2S protocol and some I2S peripherals with an ESP32. We’ll display microphone waveforms and build an MP3 player and an Internet Radio.
If your project needs a responsive user interface or has precision timing requirements, then interrupts are the key to getting it to work smoothly.
Today we will learn how to use Hardware, Pin Change and Timer Interrupts with the Arduino Uno.
