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!
Arduino IDE 2.0
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.
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.
Controlling AC Devices with Arduino
We have seen how to control DC devices with an Arduino, now it’s time to learn how to control AC equipment.
In this article I will show you a SAFE method of experimenting with AC on your workbench.
We will also build a light-activated relay and a marquis-style light chaser using solid state switches.
Shift Registers – 74HC595 & 74HC165 with Arduino
In this rather shifty article I’ll show you how to use some fundamental electronic building blocks – shift registers.
These handy devices can let you add oodles of input and output ports to your Arduino or other microcontrollers, and they’re very easy to use..
Follow along and learn how to make 74HC165 and 74HC595 shift registers work for you.
Multiple I2C Buses with an Arduino
I2C address conflicts are a common problem, and in this article, I’ll show you how to resolve them by creating multiple I2C buses with your Arduino.,/p>
I’ll demonstrate how the TCA9548A I2C Multiplexer works by using two identical OLED displays and sending them unique data even though they share the same I2C address.,/p>
