Abstract
The project aims to develop a coin -controlled mobile charging system for public places. Many people face battery drainage problems while traveling or out, and it is often difficult to find charging points. This system provides a practical solution where users can charge their mobile phone by putting a coin.When a person wants to charge their cellphone, they must insert a coin into the system. A coin detects the sensor coin and sends a heart rate signal to the microcontroller. The microcontroller then processes this signal and activates a relay, which acts as an electromachan switch. It delivers 230V, 50 Hz current to the relay charging connector, so the user can connect to his mobile phone to charge.
