Control system for adjusting the brightness level with PWM technique using visual net microcontroller-based

Abstract

A lamp is an artificial source of light produced by channeling electric current through the filament, which then heats up and produces light. Eye health experts believe that the ideal brightness of a lamp depends on ambient light. The rule must ensure that the brightness of the lights must be equivalent to the light around because, in that way, the light from the lights and surroundings will blend, and the eyes do not need to work harder. To overcome the problem, a control system was created by implementing the pulse width modulation (PWM) technique to control the brightness of the lights manually using a visual net application. Utilization of a microcontroller as a control center in controlling the brightness level of the lamp using the type of microcontroller AVR16, by displaying the PWM value on a form, designed on the visual net. Thus, it needed to set the level of light brightness to be ideal in the desired conditions.
