ESP32 Wireless Notice Board with OLED Display & Buzzer | Update Messages from Phone

In this smart IoT project, you’ll learn how to build a Wireless Notice Board using the ESP32 microcontroller, an OLED display, and an active buzzer — all controllable directly from your mobile browser!
With just a few components and simple Arduino code, you’ll create a web-based interface hosted by the ESP32 itself. You can type messages from your phone or computer, send them wirelessly, and have them instantly displayed on the OLED screen — complete with attention-grabbing buzzer alerts!
This project is perfect for schools, labs, offices, or hobby setups where real-time communication is key. No additional apps, no cloud dependency — just smart local control!
🛠️ What You’ll Learn:
✅ How to host a webpage on the ESP32
✅ How to interface an OLED display with ESP32 via I2C
✅ How to display text dynamically from the web
✅ How to control a buzzer through web interaction
✅ How to apply real-world IoT concepts with ESP32
