ABSTRACT
The objective of this project is inserting the coin using charge for your mobile phone in public places. This project is very useful to people who are all using mobile phone without charging condition in pubic places. In this project, who are all using mobile phones in outside of home are office without charging condition. The coin based mobile phone charger is very useful to that person for using coin to charge for that mobile. The IR (infrared) transmitter is used to transmit IR signal in the transmitter side. The IR receiver is used to receive the IR signal in the receiver side. Between the IR transmitter and receiver, insert a coin to change the polarity of pulse in SCU input. The SCU is used to converting low pulse to high pulse and that pulse is inverted in inverter. The 555 IC is act as a timer to produces high pulse for particular time period. Again the SCU is used to converting low pulse to high pulse and this output is give to input of driver circuit. Driver circuit is used for provide the sufficient input voltage of relay. The relay will on to activate the 230v charger, we will use charger to charge for our mobile phone.

2.0 WORKING PRINCIPLE
In our vibration alarm system, we will be having
• Infra Red sensor,
• Amplifiers,
• Comparator and
• Relay
The Infra Red sensor is used in this circuit. If there is any interrupt between the IR LEDs, the sensor senses and sends the corresponding electrical output signal to amplifier circuit.
The amplifier circuit results in further amplification of signals. The amplified signal is given to comparator. The comparator compares the incoming signal with reference. If the incoming signal is more, it operates the relay.
