Our paper deals with the plan and execution of a LASER based smart security system for discovering burglar. The principal edge of using the Laser system is that the burglar is unmindful of the fact that a security system is fix in the entry points like doors and windows since laser rays can travel long distances and are almost imperceptible. When someone go through the laser ray the circuit senses the cutoff and stumble the alarm. The alarming sound does not stop until someone turns it off manually after scrutnizing. It is one of the most economical security apparatus that can be used for indoors as well as outdoors. This apparatus centre of attention is on sending a photo of the burglar into the registered email address for sustainable verification with the help of LDR and WIFI module. It is quite competent and need very minimal power. Important terms: Arduino, LDR module, WIFI module, Piezo buzzer, message alert, laser module security

Background: The end of 2019 marked the beginning of the global pandemic COVID-19. With this global issue, all the fields of society became stagnant. The education system is no exception to it. Education sector suffered as students were sent back to homes and schools, colleges and universities were shut down. But steps were taken and the education teaching system was shifted from offline to online mode. This research project examines the educational pedagogy which has been adapted in online mode of teaching due to post COVID-19 lockdown. It seeks to discover the pros and cons of online teaching vis-a-vis the ways of offline conduct of classes. The data for the project has been gathered in the form of an online survey in which both teachers and students were given questionnaires which are used to map and understand different pedagogical choices during online teaching. It also tries to highlight the comparative value, compatibility and usefulness of digital mode of learning.
