Diseño e implementación de un sistema automático de cambio de luces principales.

Abstract

The main objective of this research work was to design and implement an automatic system for changing the main lights of a vehicle with the use of the ATMega 328P microcontroller to achieve precise and efficient control of the lights. To achieve the objectives, strategic sensors were used, among them a photoresistor, which accurately monitor the exterior luminosity. These data are channeled to the ATMega 328P microcontroller, which assumes the function of making decisions in real time, automatically adjusting the on and off of the main lights, with the activation of the relays, which act as switches that allow the passage of current. towards the respective lights as required. This process ensures optimal visibility and safe driving, while reducing the burden on the driver. The efficiency and reliability of the system undergo extensive validation through tests in real driving conditions. The results demonstrate that the system not only achieves precision control over lighting, but also demonstrates adaptability in various lighting environments. This versatility contributes to improving the driver experience and road safety. Additionally, the positive impact on the energy efficiency of the vehicle is highlighted. The microcontroller, by regulating the operation of the lights according to the conditions, reduces unnecessary energy consumption, which has considerable economic implications.
