Build Your Own Timer Plug – Automatic Mobile Charger Cut-Off Using ESP32 (Hotspot Mode) By Dinesh D | DIY Electronics & Tech Projects | Nov 2025 ⭐ Introduction Mobile batteries degrade over time, especially when overcharged overnight. While commercial timer plugs exist, they are often costly and lack flexibility. In this project, you will learn how to build a custom automatic timer plug using an ESP32 and a relay module. This timer plug switches OFF your charger automatically after a set duration — and the best part? It works completely offline. No router. No internet. Only ESP32 hotspot mode. The ESP32 creates its own WiFi Access Point. Once you connect your smartphone to it, you can open a simple webpage, enter the timer (HH:MM:SS), and the relay will turn OFF automatically when the time completes. This is a perfect beginner-friendly IoT project with real-world usefulness.          🧠 How the Timer Plug Works The ESP32 is programmed in Access Poi...

  🎯 Build Your Own RFID Attendance System Using Arduino + ESP32 + Google Sheets 📅 By Dinesh | Tech DIY Projects | May 2025     🚀 Introduction Have you ever wanted to build a smart attendance system that logs student or staff attendance directly into Google Sheets in real time? In this tutorial, I’ll show you how I created a WiFi-connected RFID attendance system using: ✅ Arduino UNO (for RFID + DFPlayer) ✅ ESP32 (for WiFi + Google Sheet logging) ✅ Google Apps Script (to act as a cloud database) Let’s dive in! 🧠 Project Concept Here’s how the system works: User scans an RFID card . Arduino detects the card, plays a welcome sound using DFPlayer, and sends the name to ESP32. ESP32 receives the name via serial and logs it to a Google Sheet using a webhook . Done! The name and timestamp are saved in the cloud. 🧰 Components Used Component Quantity Arduino UNO 1 ESP32 (DevKit v1) 1 MFRC522 RFID Reader 1 RFID Tags/Cards 2+ DFPlayer Min...
