Automobile head light intensity dimmer is the concept to increase the efficiency and reduce power consumption of the design. The user can regulate the intensity according to the need that is higher intensities as well as at lower intensities. The aim of this kit is control the intensity of lamp or any DC device that need to be regulated.
The intensity of lamp is directly proportional to the DC voltage applied across its terminals. Hence, if we control the voltage applied across its terminal, we actually can vary the intensity. Here we use microcontroller from 8051 family.
Two buttons are used as inputs to vary the intensity. The level of intensity in percentage is also displayed on the LCD. A proper driving unit is designed that is driver circuit to provide sufficient current and voltage to the device.
