| Abstract | In this study, the proponents make used of fuzzy logic for designing an automatic dimming system with the use of Arduino microcontroller. Two membership functions for light sources as inputs and one membership function for the output were used. The proponents considered Environment illumination and Room illumination as inputs. The proponents make use of occupancy sensor for the system. This sensor was used to turn on and off the lights automatically if there is an occupant within the area. The output of the membership function of the control system is used to determine the dimming percentage of LED lamps. The dimming capability of the system was made possible by Pulse Width Modulation (PWM). The duty cycle of the DC power supply for LED Lamp was controlled by PWM. The power dropped across the load is dependent on the value of the duty cycle. As the duty cycle increases, the power dropped also increases and vice versa. The control system will automatically dim the LED lamps according to the condition of the luminance in the room. The room illumination is based on the IESNA (Illumination Engineering Society of North America) which is about 300 lux. With the use of this control system, the light output can now be varied according to the required luminance of the room, which results to the decrease of electricity consumption. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
