SMART PROJECTOR ADJUSTMENT SYSTEM USING MOBILE APP.

摘要

We have an existing system where we mount projector to roof through adjustable non automated rod. Disadvantages of existing system is, it requires a manual setting after some period because direction of projection may get changed slightly or majorly due to wind flow, cleaning presentation room or lose couplings of screws used or due to change in projector etc. thus projection may get disturbed. To overcome this problem we design a mechanism and system which reset position of projector as per user requirement, using mobile app or IR remote. A major advantage of our system is we reduced human efforts and time as anyone can adjust projection using mobile application or by using IR remote. Mobile app wirelessly connected to arduino with Bluetooth or Wi-Fi .
