ESP32 NTP Clock with OLED Display | Real-Time Internet Clock using WiFi and NTP

In this beginner-friendly IoT project, you’ll learn how to create a Real-Time Internet Clock using the ESP32 WiFi module and a compact OLED display (SSD1306). The clock fetches accurate time from the internet using the NTP (Network Time Protocol) and displays a beautiful analog clock face on the OLED screen!

This project is perfect for students, makers, and anyone interested in combining WiFi connectivity with embedded graphics to build something both useful and eye-catching.

Learn how to use the ESP32’s WiFi capabilities to sync time, then draw and animate an analog clock on an OLED display — all through simple Arduino code!

🕒 What You’ll Learn:
✅ How to connect ESP32 to WiFi
✅ How to fetch real-time time using NTP
✅ How to interface an OLED (SSD1306) with ESP32 via I2C
✅ How to draw an analog clock face using Adafruit GFX
✅ How to update time every second and display hours, minutes, and seconds

🧰 Components Required:
🔹 1 x ESP32 Development Board
🔹 1 x OLED Display (SSD1306, 128x64, I2C)
🔹 Jumper Wires
🔹 Breadboard (optional)
🔹 USB Cable for Programming
