1 In thiscareer episode I’m mentioning the project which I completed during my Bachelorsof Technology in Electronics and communication Engineering stream. This is thefinal year project in fourth year second semester. The project span was of 3months that is from January 2011 to March 2011. This project was an industrialproject and completed by the great support from the recognized industry DLRL alsoknown as Defence Electronics Research Laboratory, Hyderabad, India. DefenceElectronics Research Laboratory (DLRL) was recognized in 1961 under the governmentorganization Defence Research and Development Organization. Defence ElectronicsResearch Laboratory works in regards to designing and manufacturing theElectronic systems which are used for warfare and develops these devices forTelecommunication and RADAR signal frequency levels. DLRL has many well-knownscientists and engineers as manpower.
The Industry is supported by highlyengineered hardware and software designing and development services. I was a studentmember selected from my college for the project called “Infra-Red Light Dimmer”. Background:CE3.2 The project was part of studies and was accomplished under the supervisionof an internal guide Mr P. Ramesh, Assistant Professor, Department ofElectronics and Communication, JNTU.
The purpose of the project is to designand develop a system called “IR light Dimmer”.Thedevice we develop controls light using an IR remote device. Nowadays most ofthe appliances are controlled using remote control device, people needs remotecontrol for smooth operation and for better convenience and efficiency. A remotecontrol has many operations on the device such as ON/OFF and many other for theease of use. Light dimmer adjusts the voltage of the lamp. Previous Lightdimmers consists of resistors and variable transformers.
Those methods are big,expensive and had poor efficiency. They were hard to control from remote location.Theproject was undertaken to utilize the opportunity to integrate theoreticalskills into practical learning using subject information of Analog communication,Control Systems and Embedded Systems. Saving energy is very important but manyelectronic devices consumes much energy. My aim in this was that it would bebetter if can save energy by dimming the light of the remote control lamp. As apart of the project team, I demonstrated my skills of critical thinking,problem solving ability and professional experience of engineering practices. Following are the characteristics and effortsin project planning that are required for a team to accomplish this engineeringproject at the Bachelor of Electronics Level: Understanding of Microprocessor and Microcontrollers Embedded program language for ZILOG Z8Encore and PIC16F628 Hardware configurations and specification Measurement of performance and Structural reporting. Understanding of Print circuit boards.
Knowledge on the software Protel99.
