An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention. The “automatic toll gate system project” demonstrates how simple sensors and a microcontroller can automate a real-life process like toll collection, making it an ideal project for school students and anyone just starting in the field of…

The Raspberry Pi Pico SD card module is a simple yet very handy add-on that lets you store and access a lot of data using a standard microSD card.  When interfacing the SD card module with Raspberry Pi Pico, you gain access to gigabytes of storage for sensor logging, configuration files, and time-stamped data. This comprehensive guide will show you how to build…

Over the years, I’ve collected a few Raspberry Pi boards, my trusty Pi 4 and even an older Pi 3 that was gathering dust in a drawer. Instead of letting them sit unused, I decided to give them a new life by turning them into something surprisingly practical: a Raspberry Pi WiFi router with built-in ad-blocking capabilities.

With the…

If you’ve tinkered with Raspberry Pi boards for a while, you probably know the default choice: Raspberry Pi OS. It’s lightweight, optimised, and works flawlessly for most DIY projects. But what if you could install Windows 11 on Raspberry Pi? That's exactly what I accomplished on my Raspberry Pi 4 and later on the Pi 5 and Pi 3.

That’s exactly what I set out…

Voice recognition is becoming an essential part of the Internet of Things (IoT), allowing us to control, monitor, and interact with devices hands-free. At its core,  ESP32 speech to text works by capturing audio through a microphone, processing it, and converting it into text that devices can understand. This text is then used to trigger commands, just like how…

The ESP32-CAM is one of the most popular development modules, featuring built-in Wi-Fi and a camera. With its robust 32-bit processor, it’s widely used in countless projects by hobbyists around the world! Thanks to its ability to capture images and videos, the possibilities in the Internet of Things are endless, from monitoring and surveillance to automation.

Finding the right ESP32-S3 development kit often means compromising between functionality and deployment readiness. With so many ESP32-S3 dev kits out there, we have been searching for a ready-to-deploy module that doesn’t require extra work like designing enclosures or 3D printing cases. These things can significantly increase the deployment time. One such kit we…

For wearable projects, having the right sensor module makes all the difference. As you all know, this year’s contest theme is Smart Home and Wearables, so we came up with another sensor module, the MAXREFDES117 optical heart-rate module. This device comes with integrated red and IR LEDs, making it an ideal choice for developers and enthusiasts alike. The MAXREFDES117…

There have been many development boards recently built around the ESP32-S3. Most development boards come with a display, some also include cameras and buttons, and a few have speakers and microphones. Finding one that brings all these components together without compromising on quality has been the real challenge for makers and developers. Keeping all this in mind,…

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in-one board featuring a dual-core processor, touchscreen, and compatibility with the Arduino IDE. In this tutorial, we’ll take this developer-friendly board   ESP32-…

In the world of flip-flops, the Clocked JK Flip Flop stands out with its outstanding features, such as all usable input states and the ability to be modified to imitate other flip-flops like SR, T, and D. This makes the JK Flip Flop a little better than the others. It's often called a universal flip-flop.

The JK flip-flop's main…

The Internet of Things (IoT) has revolutionised how we control devices, enabling seamless remote monitoring and operation over a network. This tutorial presents an innovative solution for remote stepper motor control, allowing you to precisely adjust its position, monitor its performance, and receive real-time feedback directly from a simple web browser. For those…
