Matrix Keypads are a great way to add a professional-looking user interface to your Arduino project. They are inexpensive, and very easy to use.
In this article I’ll show you how to use a matrix keypad with an Arduino. We will also use our keypad to build a simple electronic combination lock with an LCD display.
ESP-NOW allows you to create a private peer-to-peer network between ESP32 and ESP8266 devices.
Today we will learn how to use ESP-NOW with a bunch of ESP32 boards. We’ll also build a remote temperature sensor, and expand it to have multiple sensors.
Stop hard-coding wifi credentials in your ESP32 and ESP8266 sketches – use WiFiManager instead!
This easy-to-use wifi provisioning library eliminates the need to hard-code wifi information, and makes your projects portable!
Learn how to use WiFiManager and how to easily adapt your existing sketches to eliminate hard-coding forever!
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.
Here is a complete and detailed guide to building a Linux-based Developers Workstation from scratch!
Starting with a “barebones computer” kit we will put together a Developers Workstation that has 15 essential software applications, plus a few custom tweaks.
Make sure to download the “Cheat Sheet” to simplify your build.
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.
In this article we will start using touchscreen displays in our Arduino projects.
We’ll begin by examining how touchscreens work, and what the differences are between Capacitive and Resistive touchscreens are.
Then we’ll look at some example code and then write a simple interface of our own.
Prototyping and breadboarding is an essential skill for anyone working with electronics or experimenting with microcontrollers and microcomputers.
In this article I will show you the basics of breadboarding, along with some breadboard accessories that you are sure to find useful.
Pulse Width Modulation, or PWM, is an excellent method of controlling DC motors, however controlling large gearmotors can be expensive and difficult – but it doesn’t have to be.
Today I will introduce you to an inexpensive yet powerful H-Bridge motor driver, the Cytron MD10C.
In addition, we will see how altering the PWM frequency can improve performance tremendously.
Kodi is an advanced, open source, multimedia center that can handle all of your media requirements
In this article you will learn how to build, configure and control a Kodi multimedia center
