Weather Clock Project with OLED Display
In this comprehensive tutorial, I'll show you how to build a complete weather station using Arduino Uno, DHT11 sensor, DS1307 RTC module, and a 1.3" OLED display. The system alternates between displaying temperature & humidity and real-time date & time every 2 seconds.

PROJECT FEATURES:
Real-time temperature reading in Celsius
Humidity percentage display
Date and time with automatic RTC sync
Alternating display every 2 seconds
Clean boxed layout with perfect alignment
Error handling for sensor failures
CUSTOMIZATION IDEAS:
Add Fahrenheit temperature option
Include dew point calculation
Add max/min temperature recording
Connect to SD card for data logging
Add WiFi module for remote monitoring
TROUBLESHOOTING:
Blue screen only? Check I2C address (0x3C or 0x3D)
No sensor data? Verify DHT11 wiring and pull-up resistor
Wrong time? Replace RTC battery or set time via code
