Building an Arduino project isn’t just about making all the components talk to one another. It’s about creating an actual object or prototype out of your small creation, and giving it that extra touch that makes it unique. For this next project, we took some very basic components: a one-wire temperature sensor and a 7-segment […]

The Arduino microcontroller makes it easy to learn about electronics, but it can be hard to know where to start. Fortunately, an “Arduino Book Teaches Electronics Skills” can provide a structured approach to learning, guiding beginners through the basics and beyond. The 10 projects in this book will teach you to build, code, and invent

Parallel processing is an idea that will be familiar to most readers. Few of you will not be reading this on a device with only one processor core, and quite a few of you will have experimented with clusters of Raspberry Pi or similar SBCs. Instead of one processor doing tasks sequentially, the idea goes,
PARALLEL PROCESSING WAS NEVER QUITE DONE LIKE THIS Continue Reading
For those of us who remember LED calculators, the HP 5082-7400 series red “bubble” displays hold a special charm. Available in 3, 4, or 5-digit varieties, these multiplexed 7-segment displays provided countless hours of entertainment to those who would spell upside-down words on their pocket calculators. In case you happen to be lucky enough to

You’d be hard pressed to find a carpenter who didn’t own a hammer, or a painter that didn’t have a couple of brushes kicking around. Some tools are simply so fundamental to their respective craft that their ownership is essentially a given. The same could be said of the breadboard: if you’re working with electronics

The AEMLION is a 0.8×0.6 inch (20x15mm) PCB with the AEM10941 Solar Harvesting IC from E-peas. It efficiently converts solar energy into Li-ion battery charge, it even works with indoor light. It features 3.3V and 1.8V regulated outputs that are enabled when the battery has useful charge and a low battery warning that informs the

For the long series of articles documenting My Journey into the Cloud I used two small evaluation boards, equipped with an ESP32 32-bit controller, an antenna and a micro USB socket (the latter also serves for power supply input and provides a path for uploading programs). For newcomers, the controller can be programmed using the

A home automation system is an automating the bulk of electronic and electrical tasks within a home. It uses a combination of hardware and software to enable control and management over appliances and devices within a home. Home automation not only refers to reduce human efforts but also energy efficiency and time saving. Here we are performing home automation

Most of us would be familiar with the 16×2 Dot matrix LCD display that is used in most of the projects to display some information to the user. But these LCD displays have a lot of limitation in what they can do. In this tutorial we are going to learn about OLED displays and how

In my previous Instructable I have described how to plug the ESP-01 module into a breadboard. This is just the first step to make a cheap Arduino WiFi shield using the ESP8266 module. With few more electronic components and the WiFiEsp library you can build it for less that 10 USD. Step 1: Components Here
