4.  Not being able to focus light while working in dark environments is a problem faced in day to day life.  As a result of this, people install several number of lights in the same room which is financially unbeneficial and also contain negative energy effects.  Inability to control the light and direct it to specific areas remotely causes inefficiency and inconvenience.

5. Aim: Design user sensitive lamp that could detect the occupancy of the room and focus the light to its user. Voice commands and a computer user interface will be integrated to increase the convenience.

6. Objectives:  Reduce the cost for multiple lights in a single room.  Reduce the energy wastage  Provide more convenience for people.  Gain technical knowledge of electronics and software development

8. We used a collection of PIR sensors with a small range of sensitivity. User is detected from the heat signal originated from the body. we have devided Horizontal plane to 8 angles and set a PIR sensor per each. This detected position will be sent to the processing system of the lamp and the internal motor system will rotate the lamp in the user’s direction.

Designed a separate circuit for the stepper motor Designed the mechanical structure for the lamp and found suitable components. preparing project documentation Designed a power supply unit for the lamp. Soldering of main microcontroller board making PCBs for all circuits. Developed the structural design for the lamp. Maintaining the project book and being responsible for budget of the project. Made the final presentation. M.G.R.DilharaTo make user interface and Searched about the basic technologies that can be used for voice controlling system. A.P.D.P.Senevirathne

12. NameContributions R.G.H.PemathilakeDesigned and developed the software needed for the project using PIC programmer. Entire programming part of project. M.M.N.Sasanka Searched about the basic technologies that can be used for voice controlling system and made the user interface. R.Vyshnavipreparing project documentation. Made the interim presentation. Helped to develop the structural design.

13. Used in the lower joint of the lamp to allow the movements over the vertical axis Metal gear servo motor will be used to provide the necessary torque and to facilitate smooth movements has a rotating angle of 180 degrees.

14. Used in the base of the lamp to facilitate the complete 360 degree rotation of the lamp Allows the lamp to cover the whole area of a room. Unipolar stepper motor is used

15. Used to detect the location of the user Has a sensitivity range of approximately 100 degrees. An electric pulse of 2.7V is generated for sensing motion

16. Microchip 40 pin microcontroller used to process the signal sent from sensors and voice modules and control the lamp accordingly Reprogrammable module Speak-Up voice module used to convert analog Voice signals to digital signals and output digital pulses of our choice

17. Made with 2 transformers. Designed to power 2 motors,8 PIR sensors and other all circuits.
