Chapter 1 Introduction 1.1 Problem It seems these days that everyone has a cellular phone. Whether yours is for business purposes or personal use‚ you need an efficient way of charging the battery in the phone. But‚ like most people‚ you probably don’t like being dependent on the main supply for charging your cell phone battery or you don’t have the time to recharge your cell phone battery. As technology has advanced and made our phones smaller and easier to use‚ we still have one of the original

POWER SAVER FOR ADVERTISEMENT HOARDINGS USING RTC In this competitive world human cannot spare his time to perform his daily activities manually without any fail. The most important thing he forgets is to switch off the room lights wherever not required. With this‚ even the power will be wasted up to some extent. This can be seen more effectively in the case of commercial sign boards. This project gives the best solution for electrical power wastage. Also the manual operation is completely eliminated
