The project was not completed foe lack of cumunication. Comunication is both sides so it was also my fault.

Control of Light Intensity of LEDs for Outdoor Lighting

International Journal of Science, Engineering and Technology Research (IJSETR)
This paper aims to present an effective approach to design a system for outdoor LED lighting in which user can control the light intensity of the LEDs. Since the light intensity of LEDs is directly proportional through the current passing through them, the proposed system can be implemented using constant current regulators to limit the flow of current throughthe LEDs based on the single PWM produced by an MCU. The circuit is a constant current source, which implies that the LED brightness would be constant
