DescriptionThis Mobile Charger Kit aims to provide prepaid mobile charging in public areas by inserting a coin. For the Kit coin-based prepaid charging, the first block is the power supply. The input voltage is 230V AC, which is step down using the transformer (12-0-12). The 12V AC input is fed to the bridge diode to give 12V pulsating DC. This DC voltage is filtered through the capacitor to remove the ripples. The filtered DC is fed to the 7805 regulators to fetch +5v regulated output.
The objective of the kit Coin Based Prepaid Charger is to transmit an IR (infrared) signal on the transmitter side using an IR transmitter and the IR receiver is used to receive the IR signal on the receiver side. This circuit uses an Infra-Red sensor between the IR transmitter and receiver. If there is an interruption between the IR LEDs, the sensor senses and sends a corresponding electrical output signal to the amplifier. The amplifier circuit results in further amplification of signals. The amplified signal is given to the comparator. The comparator compares the incoming signal with a 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 acting as a timer to produce a high pulse for a particular time period. The driver circuit is used for providing sufficient input voltage of the relay. The relay will be activating the 230v Sensor Based Charger through which we can charge our mobile.

But you can made easily
It was Amazing connecpt to use consume the chharginng time
Good for above 15
The project was good and fun to build. It could have better explained instructions. Works well.
Very nice kit
