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!
Driving DC Motors with Microcontrollers
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.LED Displays with Arduino
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.
e-Paper with Arduino & Raspberry Pi
e-Paper displays have a number of unique features, such as being visible in broad daylight, consuming very little current, and retaining their image when powered down. But they also have some disadvantages – they have poor refresh rates, limited color capability, and are more expensive than other display types.
in some applications, however, e-Paper is a perfect choice, and today we will see how to use these displays with both an Arduino and Raspberry Pi.
Arduino IDE 2.0
Introducing the new Arduino IDE 2.0 (Release Candidate 3), the improved IDE from the folks at Arduino.
In this article we will install the IDE, check out its features, and even expose a few bugs!
MyoWare Muscle Sensor
Today we will learn about electromyography by working with a MyoWare Muscle Sensor.
We’ll see how to use this device and its shields in both stand-alone mode and with an Arduino.
Waterproof Ultrasonic Sensors
The JSN-SR04T and A02YYUW are a couple of inexpensive waterproof ultrasonic distance sensors. They are easy to use, and have several advantages over the popular HC-SR04 sensor.
In this article I’ll show you how they work and how to use them with an Arduino Uno.
Arduino Nano RP2040 Connect – Arduino meets Raspberry Pi
The much-anticipated Arduino Nano RP2040 Connect board has a Raspberry Pi RP2040 MCU with ESP32-based WiFi and Bluetooth. The board also sports a 6-axis IMU with Machine Learning, a built-in MEMS Microphone, and a Cryptographic Coprocessor.
Today we will learn how to set up our development environment to work with this exciting new board, and we’ll run a few Arduino-supplied example sketches.
