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.
DC Servo Motor Guide – With ESP32 & Arduino
Arduino GIGA Display Shield
The Arduino GIGA Display Shield is a powerful TFT display with integrated IMU, microphone and RGB LED. This capacitive touchscreen display even has a connector for a camera.
Today we will see how to use this display and its advanced features to build powerful user interfaces.
IR Remotes Revisited – 2023
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.
Arduino Nano ESP32
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.
Arduino Uno R4 – Minima & WiFi
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.
Arduino GIGA R1 WiFi
The new Arduino GIGA is the most powerful microcontroller that Arduino has ever produced.
Today we will take a first look at this monster, which has the same form factor as the Arduino Mega.
Of course, we’ll test out some of the more unique features of this board as well.
Driving DC Motors with Microcontrollers
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 Air Quality with Microcontrollers
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
Using GC9A01 Round LCD Modules
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.
Using Arduino Interrupts – Hardware, Pin Change and Timer
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.
