Abstract: A mobile phone charging system based on a coin acceptor system connected with solar panel and battery system is a great service to the public at open places. The coin acceptor thus also provides a great profit to the provider and we can install this in any places easily where people gather more such as railway stations, bus terminals, malls, etc. as this system is portable. The energy is obtained from solar panel, so the running cost is also very low. The system is designed with ARDUINO ATMEGA 32 microcontrollers, thus the input pulses while coin acceptor is active is sent to the battery module and mobile phone can be charged. The system will work even in cloudy days because a battery is also included in it.
