Rfid Based Mobile Charging Using Arduino

DOWNLOAD ABSTRACT

AIM:

Design and development of RFID based mobile charging using Arduino.

PURPOSE:

We can charge mobile easily in homes or offices. But when we go outside it is difficult to charge mobile phones. There are so many shops in and around at outside. They can install this kind of systems and make money. Here we proposed system like RFID based mobile charging using Arduino.

DESCRIPTION:

RFID reader (EM-18) Interfaced to Arduino through UART interfaces. Charger cable can be controlled by relay which is connected to Arduino digital pin. Buzzer connected to Arduino digital pin.

WORKING:

Here we have 4 valid cards and one invalid card. If we swipe valid card then relay will be ON and mobile charger will be ON. It will remains in ON stage for 5 minutes and then OFF. If we want to disconnect from middle of charging then we have to swipe RFID card 2^nd time. For invalid RFID card buzzer will be ON.
