Home Energy Saver with RTC – Auto Light Brightness Bar | Arduino + LCD + Time Control (No Talking)
💡 Build a Smart Home Energy Saver with Arduino!
This project uses a real-time clock (RTC) to automatically control light brightness throughout the day. Instead of using float switches or sensors, this version displays brightness using a 3-LED bar — giving a clear visual of light levels based on time.
🧠 Features:
RTC-based automatic control (DS1307)
3-LED bar shows brightness levels:
-“🔴 = Low (33%)”
"🔴🔴 = Medium (66%)”
-"🔴🔴🔴 = Full Brightness (100%)”
LCD displays time and brightness status
Energy-saving logic simulated in Wokwi
No talking – just clean, clear visuals
✅ Components Used:
Arduino Uno
RTC DS1307
I²C LCD 16x2
3 LEDs (Red, Yellow, Green)
220Ω resistors
Breadboard + jumper wires
📍 Simulated in Wokwi website
🎯 Great for:
Smart home projects
Time-controlled lighting
Arduino learners and educators
🌊 Features calming wave sounds and a smooth, no-talking simulation style — ideal for focused learning or background watching.
