Hello there ! I am Vaishnavi !

Welcome to this tutorial on ‘Automotive Light Control’ project. 

The project has been simulated on Tinkercad and we have provided you with a detailed video tutorial for better understanding. 

Tinkercad is a free-of-charge, online 3D modeling program that runs in a web browser, known for its simplicity and ease of use. Since it became available in 2011 it has become a popular platform for creating models for 3D printing as well as an entry-level introduction to constructive solid geometry in schools. It can also be used to simulate Arduino based Circuits by coding the Arduino in the simulation environment itself.

The project is about controlling the following 3 lights,

1. Parking light

2. Fog light

3. Head light 

While Parking light and Fog light are controlled by their dedicated switches, Head light could be operated in Manual as well as AUTO mode.

The headlight in Manual mode (when AUTO mode is turned off) can be controlled by operating a dedicated switch just like in the case of Parking light and Fog light. But in AUTO mode, the head light is solely controlled by the ambient light conditions. 

The circuit consists of three 12v lamps designated as Parking light, Fog light and Head light. These lamps are operating on an external power supply but are controlled by the Arduino’s digital output pins through relays.

We have used four switches in total. Three of them to turn ON/OFF the three lights and one to activate/de-activate the AUTO mode of the head light.

Here is the circuit diagram :
