Abstract :

The Rapid Growth Of Public Utility Systems Has Increased The Demand For Efficient Mobile Charging Solutions In Public Places. This Project Presents A Coin-based Mobile Charging System Using IoT Concepts That Automates The Charging Process. The System Allows Users To Charge Mobile Phones By Inserting Coins In Locations Such As Railway Stations, Bus Stands, And Shopping Complexes. A Coin Recognition Module Is Used To Detect The Inserted Coin And Generate A Signal. The Microcontroller Processes The Signal And Controls The Charging Operation. An LCD Display Shows The Remaining Charging Time For User Convenience. The System Provides A Fixed Charging Duration Of 5 Minutes Per Coin And Maintains A Regulated 5V Power Supply. If An Additional Coin Is Inserted During Charging, The Time Is Extended Instead Of Resetting. Overall, The System Is Simple, Costeffective, And Suitable For Public Charging Applications
