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.
Follow along as I put together an indoor/outdoor robotics project, an autonomous rover. I’ll be adding more articles and the occasional video to this section, to show you how I’m progressing with this build. Introduction This is the beginning of
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!
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.
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.
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.
Today we will be putting together a robot car based upon the popular ESP32CAM module.
Our car will have a WiFi remote control and will stream video, so you can see where you are going when you drive it!
In order to learn to code in MicroPython or CircuitPython you are going to need to get a firm foundation in Python.
In this article I will give you a list of resources like websites, YouTube videos, Udemy courses and books that will help you become an expert in Python.
And the best part is that all of these resources are completely free!
CircuitPython is an easy-to-use language with hundreds of libraries for microcontrollers. Today we will be using CircuitPython with the Raspberry Pi Pico
With over 300 libraries already to go CircuitPython makes it easy to expose the power of the Raspberry Pi Pico.
Today we’ll see how to install CircuitPython and how to use it to build a keyboard emulator, a mouse emulator, work with MicroSD cards and flash some addressable RGB lights.
