The ESP Wi-Fi modules are microcontrollers with Wi-Fi and Bluetooth (not all models) capability, developed by Espressif Systems. It consists of many development boards like ESP8266-01, ESP8266, NodeMCU, ESP12, ESP32 etc. All the development boards can be easily programmed using Arduino IDE and can be used in a variety of applications like Home Automation, Internet of things (IoT), Smart devices etc.. The below list consists of a large collection of ESP8266 projects with circuit diagram, code and hardware demonstration. You can also check out the Arduino ESP8266 projects if you have to interface an ESP with Arduino board.
We recently came across reports covered by news outlets about electric vehicles, specifically e-rickshaws, being remotely hacked and stalled in the middle of busy roads. The attackers were using Android apps, some of which were available on the Google Play Store under names like BAT-BMS, Epoch Li-on and Overkill Solar. These apps were apparently able to connect to some specific brands of the…
With football fever reaching its peak, DHK DUDE from youtube built this pocket-sized, real-time World Cup score gadget for his desk. Powered by a Wemos D1 Mini microcontroller, this custom IoT gadget utilizes built-in Wi-Fi to seamlessly connect to the internet, fetching live match telemetry, group fixtures, and team data directly through web APIs. Like every maker…
In this project, we are going to build a Smart Farming System using IoT. The objective of this project is to offer assistance to farmers in getting Live Data (Temperature, Humidity, Soil Moisture, and Soil Temperature) for efficient environment monitoring, which will enable them to increase their overall yield and quality of products. This smart agriculture using an IoT…
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…
In this project, we'll explore an IoT-based irrigation system using the ESP32 board and Blynk app. It's a project based on the Internet of Things (IoT), the smart irrigation system offers numerous possibilities to automate the entire irrigation process. Here, we're creating a plot-based smart irrigation system using the ESP32 Controller, a soil moisture sensor, a…
This guide shows you how to build a motion detection system that sends instant WhatsApp alerts using the compact XIAO-ESP32 development board. When the IR sensor detects movement, the board immediately transmits a notification to your phone through the CircuitDigest Cloud platform. This wireless approach eliminates the need for GSM hardware or SIM cards, relying…
This project shows how to send instant WhatsApp alerts from a Raspberry Pi Pico W using WiFi and CircuitDigest Cloud WhatsApp API. The Pico W reads data from a rain sensor and, when moisture is detected, sends a notification directly to your WhatsApp. No GSM module, SIM card, or cellular hardware is required and everything works over a secure HTTPS request. The same WhatsApp notification…
In this tutorial, you will learn how to send WhatsApp messages from Arduino UNO R4 WiFi using the CircuitDigest Cloud Whastapp API. Instead of using a GSM module, SIM card, or complex WhatsApp Business API setup, this method allows your Arduino to send alerts over WiFi using a simple HTTPS request. This makes it much easier and more cost-effective to add real-time…

Smart home systems are increasingly adopting intelligent sensing technologies to understand indoor environments and automatically adapt to the user's needs. Among these technologies, cameras play a critical role in tasks such as human presence detection, room occupancy monitoring, and context-aware automation for…
At CircuitDigest, we've been creating and sharing Internet of Things (IoT) projects with our community for a long time. A crucial part of these projects is enabling communication between IoT devices and end users, and when it comes to simple notifications, nothing beats the practicality of sending an SMS.
However, sending an SMS from…
In many IoT applications, there are situations where the sensor data needs to monitor continuously, and the simplest way to do that is by enabling an ESP8266 webserver which serves an HTML webpage; but the problem with this methodology is that the web browser needs to be refreshed at a certain time interval to get an updated sensor data. This is not only…
Have you ever wanted to build your own IoT-based Weather Monitoring Station? Imagine monitoring real-time temperature, humidity levels, atmospheric pressure, rainfall detection, air quality index (AQI), and more—right from your local network. With the power of the Arduino UNO R4 WiFi, you can create a dynamic weather dashboard web page that displays all your environmental data in real-time…
