Imagine a smart doorbell that works even when your internet goes down. No cloud dependencies, no Wi-Fi outages—just two ESP boards talking directly to each other, instantly. That’s exactly what we’re going to build today using ESP-NOW, Espressif’s incredibly efficient wireless protocol. Here’s what our smart doorbell system will do: Let’s get building! What You’ll
ESP-NOW is a highly versatile and lightweight wireless communication protocol developed by Espressif. Unlike standard Wi-Fi or Bluetooth, it allows multiple ESP32 and ESP8266 devices to exchange data directly without needing a router, internet connection, or complex network pairing. This makes it perfect for IoT projects, sensor networks, home automation, robotics, and battery-powered devices. In
Keeping track of your Rakats, Rukoo, and Sujood during Salah can be a great solution, especially during long prayers. A microcontroller like Arduino with some sensors can be used to create an innovative Smart Prayer Mat capable of detecting prayer movements such as Rukoo and Sujood. In this Guide, we will build a Smart Prayer
The Wemos D1 Mini has become one of the most popular Wi-Fi-enabled microcontroller boards for IoT projects. Based on the ESP8266 chip, this tiny yet powerful board allows makers, students, and engineers to create wireless projects with ease. In this guide, you’ll learn everything you need to know to get started with the Wemos D1
Want to make your old-school light switch smart without replacing it? So, Today we build a smart WiFi-controlled light switch using an Espressif Systems ESP8266 board and two servo motors.The ESP8266 creates a simple web server that allows you to control a physical wall light switch directly from your smartphone or computer. 🛠 Components Required:
Introduction Imagine being able to turn on a light in your living room while sitting on a beach in Thailand. Or check the temperature of your greenhouse from your office. With an ESP32 and Google Firebase, this isn’t science fiction — it’s surprisingly simple. So, I’ll show you how to control an LED (or any
