Arduino based Solar Light System (Rudra)

Solar lighting is very efficient for specially outdoor lighting.So i have designed this project and manage to work very efficiently.

Materials Required

• Arduino Uno
• Mosfet Module
• DS3231 RTC module
• Voltage Sensor
• 12v 10w Led chip
• 11.1v 18650 battery pack

Circuit Diagram

The complete project can be built on top of a breadboard with some connecting wires. The circuit diagram made using fritzing that shows the breadboard view of the project is shown below

Understanding the main idea

Basically the whole project is time based one.So i have used DS3231 RTC module which allows to interact with real time clock.So the system change the brightness of the led according to the time and it's battery voltage.

Programming the Arduino

The complete Arduino Program is given at the end of this page you can jump down if you eager or read further to understand how the code works.
