📌 Introduction If you’re new to electronics and coding, starting with traditional Arduino code can feel intimidating. That’s where mBlock comes in—a visual, drag-and-drop programming platform that makes learning Arduino simple and fun. In this guide, you’ll learn how to set up mBlock, connect your Arduino board, and create your first project without writing a

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

The ESP32-CAM is a powerful yet affordable development board with a built-in camera. In this new guide, you’ll learn how to capture a photo with the ESP32-CAM and send it as an email attachment using the ESP Mail Client library. To save power, the device enters deep sleep mode after sending the email and wakes up when

The GC9A01 round TFT display is not just another screen. Unlike standard rectangular screens, a circular LCD adds a touch of style and sophistication — it’s a powerful way to create modern, smartwatch-style user interfaces in your electronics projects. In this guide, I’ll walk you through everything you need to know: from wiring it up

Security systems are becoming an essential part of modern homes and offices. Instead of traditional keys, RFID technology offers a simple and secure way to control access. So let’s build a complete RFID door lock system using Arduino, an RC522 RFID reader, and a solenoid door lock. This system allows access only to authorized RFID

Introduction In this new Project, we will transform an ESP32 into a powerful smart home controller. By the end, you will be able to control 4 appliances (like lights or fans) in two ways: We will use the ESP32’s built-in Wi-Fi to host a local web server. No third-party cloud services are required, which means
