Single Axis Solar Sun Tracker with Voltage Display

Automatic Solar Sun Tracker with Smart Day-Night Light Control Overview: The Automatic Solar Sun Tracker with Smart Day-Night Light Control from Bigyan Project is an advanced educational science project that tracks sunlight and generates power efficiently. The system automatically rotates the solar panel toward the sunlight using dual 5mm LDR sensors. When sunlight is detected, a red 5mm LED indicator glows to show that the battery is charging, and the LCD display shows the generated voltage in real time. When sunlight is absent, the LCD display turns blank, the red charging LED turns off, and the connected home LED light automatically turns on, acting as a smart night lamp. This makes the project not only educational but also functional and practical for real-world learning on solar automation.
