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 GC9A01 Round LCD Modules
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.
Build a Pico “Uno” – Prototyping with the Pico
The Raspberry Pi Pico is a very powerful microcontroller, especially when compared to an Arduino Uno. Yet most of the time we reach for a board to test with, we pick an Uno! This is because the Uno is easier to prototype with.
Well, today we’ll change all that and build three different “Pico Uno” boards that have the power of the RP2040 and the ease of use of an Arduino Uno.
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.
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.
