The objective of this kit coin based prepaid charger is inserting the coin using charge for your mobile phone in public places. In this kit coin based prepaid charger the first block is power supply in which the input is 230V AC which is step down using the transformer (12-0-12) .The 12V ac input is fed to the bridge diode to gives 12V pulsating DC. This DC voltage is filtered through the capacitor to remove the ripples. The filtered DC is fed to 7805 regulator to fetch +5v regulated output.
The objective of this kit coin based prepaid charger 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, 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. Insert a coin to change the polarity of pulse in 555 inputs. The 555 IC is act as a timer to produces high pulse for particular time period. Driver circuit is used for provide the sufficient input voltage of relay. The relay will on to activate the 230v charger through which we can charge our mobile.
