1. AUTOMATIC CELL PHONE CHARGEER WITH PAY SYSTEM
ABSTRACT:
 Our objective is to design and develop a charger system normally “AUTOMATIC CELL
PHONE CHARGER WITH PAY SYSTEM”.
 For this project cell phone automatically charged with the help of charger circuit which
interfaced with coin box arrangement.
 The control mechanism contains the microcontroller unit, LCD display, cell phone charger
unit and key pad.
SCOPE OF THE PROJECT:
This is an era of automation where it is broadly defined as replacement of manual effort by mechanical
power in all degrees of automation. The operation remains an essential part of the system although with
changing demands on physical input as the degree of mechanization is increased.
Degrees of automation are of two types, viz.
Full automation.
Semi automation.
In semi automation a combination of manual effort and mechanical power is required whereas in full
automation human participation is very negligible.
