SUMMARY
The aim of this project is to insert a coin, with a charge to your mobile phone in a public place. This project is very useful for people who are using a mobile phone without charging the State in pubic places. In this project, which all use mobile phones in outside the home are the Office without charge status. Coin based mobile phone charger is very useful for this person to use a coin to charge for this mobile phone.(IR) INFRARED sensor is used for IR transmission in the transmitting party. IR receiver is used to receive IR signal on the receiving side. Between the IR transmitter and receiver, insert a coin to change the polarity of the pulse in the SCU login.SCU is used to convert the low pulse high pulse rate and pulse inverter is complemented. 555 IC timer as produces high-quality impetus for a certain period of time. Again the SCU used to convert low pulse high pulse rate and the output to the input circuits of the driver. The driver circuit is used to ensure that the input voltage of the relay a relay to activate 230V battery charger, we'll use the charger for charging for our mobile phone.

PRINCIPLE OF WORK
CHAPTER 02
2.0 PRINCIPLE of OPERATION
In our system, we will have a vibration
• Infrared sensor
• Amplifiers,
• comparator and
• Relay
Infrared sensor used in this schema. If there is any interruption between the IR LEDs, sensor senses and sends the appropriate electrical signal output circuit of the amplifier.
Amplifier scheme results in further strengthening of signals. Amplified signal is the comparator. The comparator compares the input signal with the reference. If the input signal more, he works the relay.
