Proximity sensors can be described as one of a kind switches that detect a nearby object with the help of light, electromagnetic field, or sound. Typically, these types of devices are designed to detect nearby subjects, and often it's the practical application that most of these sensors are going to be used in. But there are circumstances where the subject is far away from…
Drones have rapidly evolved from niche hobbies to versatile tools with a wide range of applications, from photography to agriculture or even for defence and military purposes. Building a DIY ESP32 drone project is an affordable entry point into drone technology, with costs ranging from pocket change to commercial-grade systems. Even though the basic principle…
A generic AC fan regulator circuit is essentially used to vary the speed of the fan. In this project, we will build our own fan regulator with minimum components and for better efficiency. Generally, the fan generates a humming noise when brought to use with different fan regulator circuits, our circuit uses DIAC and a TRIAC and produces minimum…
The need for home security alarm systems nowadays is a serious demand. As the number of crimes is increasing every day, there has to be something that will keep us safe. A motion sensor dog barking alarm can be a great choice for that purpose. The sound will alert you when someone approaches the house. They can also deter burglars from deciding to enter a home.

The planet Mars has captivated our imagination for centuries, and the idea of sending rovers to explore its surface has fueled our curiosity even further. In this project, we will delve into the exciting world of robotics and demonstrate how to build an Arduino-based Mars rover capable of traversing various terrains. So, fasten your…
In modern day, the need for surveillance systems is increasing rapidly. We have a lot of recognized brands that offer such solutions. But can we extend the capabilities of a $5 ESP32-CAM module to build something similar?In this project, we are going to build an AI-Based No Parking Alert System using ESP32-CAM, in which, if someone parks their vehicle in front of the…
There are many human identification systems that use signatures, fingerprints, voice, hand geometry, face recognition, etc. to identify persons but none of them can detect and recognize the persons in public areas such as airports, retail stores, and railway stations except the Face Recognition System.
Face recognition systems can, not only be…
Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back radio waves or IR light from objects and calculate speed based on time taken for the light or wave to reflect. In this article, we will learn how to similar speed…
In this project, we’re making an ordinary two-wheeler helmet smart using an RF Transmitter & Receiver. The best part: this Arduino-based smart helmet is simple to build and does not require advanced engineering knowledge or complex components.
Smart Helmet using Arduino - Quick OverviewBuild Time: 6-8 hours | Cost: $40-60 | Difficulty:…
Drones are amazing little machines, but most of the time they are controlled using remotes filled with buttons and joysticks. While experimenting with our LiteWing drone, we started wondering, wouldn’t it be cool if the drone could simply listen to what we say? That idea eventually turned into this project. We built a voice controlled drone using ESP32 for the…
This ESP32 WhatsApp notification project shows how to send real-time WhatsApp alerts directly from an ESP32 using WiFi and the CircuitDigest Cloud WhatsApp API. The ESP32 reads sensor data, checks for a defined condition such as high temperature or motion detection, and immediately pushes a WhatsApp alert to your phone. And the best part is, you do not need a…
An inverter is a circuit that converts Direct Current (DC) to Alternating Current (AC). A PWM inverter is a type of circuit that uses modified square waves to simulate the effects of Alternating Current (AC), which is suitable for powering most of your household appliances. I say most-of because there generally exist two types of inverters, the first type is the so-called a…
