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.
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!
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.
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.
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.
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.
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.
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.
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.
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.
