ABSTRACT
The objective of this project is inserting the coin using charge for your mobile phone in public places. This project is very useful to people who are all using mobile phone without charging condition in public places. In this project, who are all using mobile phones in outside of home are office without charging condition. The coin based mobile phone charger is very useful to that person for using coin to charge for that mobile. A sensor system is used to detect the presence of coin. It may be of different type (IR sensor, Using LDR etc...). The coin is inserted between the transmitted and received signal.
When a signal came from sensor unit, the microcontroller activates the charger unit for a predefined time. After that it will reset to normal case. Driver circuit is used for provide the sufficient input voltage of relay. The relay will on to activate the 230v charger, we will use charger to charge for our mobile phone.
