Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using Arduino. This LPG gas leak detector uses an Arduino Uno and MQ-5 gas sensor to detect gas levels in the air and activates a buzzer and LED to alert users when a leak is…
Persistence of Viasion is a fundamental principle that allows our eyes to perceive continuous motion from separate images, a concept crucial to the illusion of motion in cinema. When I was a kid, I was always fascinated with it. So, in this project, we are going to use this fascinating optical phenomenon to create a cool-looking POV Display. You must have seen a lot…
Digital load scales are another miracle of modern-day engineering and design. Yes, we are talking about the weighing scale we often see in most of the grocery stores and other places, but have you ever wondered how a weight scale work? To answer that question, in this project, we are going to take a look at the load cell and its working. Finally, we will be building a…
An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive components can replace expensive commercial systems, giving you complete control over features while learning valuable skills in embedded programming and circuit design…
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. However, these LCD displays have a lot of limitations in what they can do. In this tutorial, we are going to learn about OLED displays and how to use them in your Arduino Projects. There are many types of OLED displays available in the market and…
Do you remember the old classic 8-bit games? Perhaps you enjoyed your leisure time in front of an early home computer or video game system. They were so nostalgic, and every kid in that era loved them. Now they are replaced with modern high-end graphics and game dynamics. Yet many people still love to play those classic games.…
Let's say you are trying to build a remote IoT data monitoring system; the first problem you will face is how to get a proper internet connection for your device. Whether you want to get notified when someone enters your room or you want to water your plants from miles away, the internet is always a problem. In this type of situation, the SIM800L GSM/GPRS Module…
Every Electronic device or product requires a reliable power supply unit (PSU) to operate it. Almost all devices in our home, like TV, Printer, Music Player etc. consists of a power supply unit built into it which converts the AC mains voltage to a suitable level of DC voltage for them to operate. The most commonly used of type of power supply circuit is the SMPS (Switching…
Amplitude modulation (AM) was first introduced to enable long-range wireless audio communication, representing a major advancement over wireless telegraphy using spark-gap transmitters. Understanding what is amplitude modulation and how it works is fundamental for electronics engineering students and professionals working with radio frequency circuits. This…
Want instant SMS alerts from your ESP32 without relying on a bulky GSM module? Whether it's motion detection, a sudden temperature spike, or an unauthorized locker door opening, your ESP32 can now send real-time SMS notifications straight to your phone, using just Wi-Fi and a free API from Circuit Digest Cloud.

Motion sensor circuits are there on the Internet for quite a while now. These circuits are mainly used to drive AC load (like lights, fans) in home automation or IoT projects. It is also very common in manufacturing industries, like on conveyor belts where the presence/position of a particular object has to be detected.
So, in this tutorial, we are…
A flip-flop in digital electronics is formally defined as "A bistable device with synchronous inputs that changes state only at specified transitions of a clock signal" (IEEE Standard 91/1984)
In general, flip-flops are fundamental components in digital electronics, capable of functioning as 1-bit memory storage devices. Unlike…
