Solar based Draw Coin Draw Power Using Arduino
Abstract
This paper describes coin based mobile charger using system. Mobile phone’s become a major source of business/personal communication; the mobile phone business is currently worth billions of dollars, and supports millions of phones. The need to provide a public charging service is essential. Many critics argued that a public mobile phone charging service is not a lucrative business because most users can charge their phones at home, in their office or in their cars. Coin operated mobile phone charger is new business milestone because many are attending business conventions and forgetting their charger at home or in hotel rooms. Students and many people use the public transportation that don’t know that their level of their battery is low are prospective customers for coin operated mobile phone charger service. Recommended locations include: Hotels, Conference centres, Exhibition halls, Serviced offices, Exchange halls, Leisure centres, Health clubs, Training centres, Golf clubs, Retail outlets, Shopping malls, Internet cafes, Universities, Colleges, Hall of residence, Airports, Train terminals, etc., so that the mobile phone users can reactivate a low or dead battery by simply plugging in and charging for one rupee. This is designed based on Arduino microcontroller that does the countdown timings for a period of 3 minutes with LCD displays showing the actual time left. During the timing period a relay output is latched and finishing timing in progress.
