Most existing home automation systems emphasize remote access rather than intelligent automation. Users are required to manually select modes, configure schedules, or control devices individually through applications. This approach makes the system reactive and increases operational effort. From a system design…

Hi everyone!, my project is a standalone Smart Library Kiosk designed to replace the traditional librarian counter with a self-service system. Built on the Adafruit Memento Development Board (from DigiKey) with an ESP32-S3 chip, it runs independently-currently powered via laptop but easily adaptable to a 3.7V LiPo…
The Smart SMS Alert System using Seeed Studio Xiao ESP32 is one of the compact IoT projects that uses an HC-SR04 ultrasonic sensor to detect nearby movement. The system acts like a motion detector whenever something moves close to the sensor and crosses the set threshold. The ESP32 Seeed Studio module instantly triggers an SMS alert. The ESP32 can send real-time SMS…
Ever thought about how you could monitor the household energy usage of your home remotely without heavy hardware or a complex setup? To make this idea practical, we came up with this project: an IoT based Smart Energy Meter using MQTT with SMS alert. Using the PZEM-004T sensor with ESP32, this smart energy meter using IoT provides real-time tracking of voltage…
This project involves creating your own GPS tracker using the Xiao-ESP32-S3 microcontroller. Usually, making a GPS tracker needs extra parts like a SIM card, a GSM module, and other communication tools to send location data to a phone or computer. Building a GPS tracker with Seeed Studio XIAO has never been easier. But that’s not an issue anymore. At Circuit Digest,…
ESP32 text to speech becomes a really helpful feature that can turn an embedded project from good to really useful. Whether you're building a handheld device, automation panel, safety monitor, or educational tool, implementing text to speech in ESP32 makes your project more accessible and user-friendly. Over time, we’ve tried many different ways to do this. Our…
In addition to causing delays, fuel waste, and increased pollution, traffic jams and congestion are serious concerns in cities and can occasionally result in fatalities. Traditional traffic light systems operate on fixed time intervals, often leading to unnecessary delays during periods of low traffic. To overcome this issue, in a smart traffic management system…
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.

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-…
Combining the dual-core processing capabilities of the ESP32 with the reliability of GSM connectivity, the ESP32 GPS tracker with SIM800L is the perfect solution for real-time position tracking. Unlike Wi-Fi-only solutions, this ESP32 GSM GPS system will work anywhere there is cellular coverage, because it does not rely on Wi-Fi. The NEO 6M GPS module with ESP32, in…
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…
