PROJECT DESCRIPTION

The main concept of this project is to provide a flashlight as an indication to guide the navigators in  shipyards or sea shores to their destination. The light glows based on the concept of  pulse width modulation. It is also used in middle of the sea to warn ships about the hidden rocks.

A programmable microcontroller from the 8051 family is engaged to provide flashing light at periodical intervals as per the practice followed at sea shores, shipyards, etc. A low-voltage lamp of 12V is driven by a power MOSFET in PWM mode, which is derived from a microcontroller.

The duty cycle of the PWM has to be changed depending on the type of application. As the controller gives only 5v drive, it is not possible for the MOSFET to be reliably switched ON at that voltage. An interfacing transistor is used between the controller output and the MOSFET for driving the same.

Furthermore, in future the project can be enhanced by using a high-power 230V lamp in combination with a solid-state switching for better visibility.
