Coin Based Mobile Charging System

Abstract

This project describes coin based mobile charger, 
which provides service in public areas. In rural 
areas partial grid power is available in a day, to 
overcome this solar charging is a suitable method. 
This technique can be used in railway stations, in 
bus stands, in market. The basic design of this 
system is to provide uninterrupted communication 
to the user if he forgets to charge his battery or if 
the battery becomes flat. Charging of mobile can be 
accomplished by single coin insertion of 1re or 5re 
coin. Arduino nano is used for detection of inserted 
coin using ir sensor and controlling charging period 
for specific time user can continue the charging 
inserting more coin. Arduino software is installed 
in the computer and so that we can edit and upload 
the program according to the application. This 
Arduino software supports C & C++ programming 
language.
