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.
MyoWare Muscle Sensor
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.
Radio Control – Use the Flysky FS-I6X with Arduino & Build an RC Car
Today we will learn how RC Remote controls work, and how we can use them with an Arduino.
After learning two different ways of interfacing with the Flysky receiver, we will build a small robot car.
Our car will have two different modes – Normal & Spin. You’ll have to read the article or watch the video to find out what that means!
Getting Started with the Arduino IoT Cloud
Today we will look at the Arduino IoT Cloud, an online application for building Internet of Things (IoT) devices.
I’ll show you how to get an account set up, how to configure your workstation, and how to build your first “Thing”.
The cloud was recently updated, so now even free plan users can work with the ESP32, and I’ll show you how to do that as well.
Using GPS Modules with Arduino & Raspberry Pi
Learn to use common GPS positioning modules in your Arduino and Raspberry Pi projects.
Today we will see how satellite positioning systems work, and how to use GPS modules in our projects.
We’ll also build a GPS Logger to track our movements, then display our data on Google Maps.
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.
Arduino Nano 33 IoT Board
Today we will look at the Arduino Nano 33 IoT board, an updated 32-bit version of the original Nano. This board combines WiFi, Bluetooth, an IMU, and a Real-Time Clock in a package identical to its older cousin.
We’ll see how to set up the board with the Arduino IDE and how to use all of its features.
I’ll be using this board in a few IoT projects, so it’s a good idea to get familiar with it.
Measure DC Voltage and Current with an Arduino
In this first of a two-part series we will learn how to measure both DC voltage and DC current using an Arduino Uno. Although the examples all use the Uno, what we learn here can be applied to any microcontroller.
The second part of the series will, of course, focus on Alternating Current.
Getting Started with PlatformIO
Today we will look at PlatformIO, an alternate IDE for working with the Arduino and many other microcontrollers.
You’ll learn how to install PlatformIO under Visual Studio Code, and also how to use it to program for the Arduino Uno, The ESP32 and Seeeduino XIAO.
Once you get used to it you’ll see that PlatformIO has many advantages over the Arduino IDE.
Meet the Seeeduino XIAO
Come and meet the XIAO, a tiny 32-bit Arduino-compatible microcontroller that goes for only 5 dollars!
This amazing little device outperforms the Arduino AVR boards and offers features like an analog output and 10 PWM pins.
We will explore the XIAO using the Arduino IDE and see how easy it is to use.
